Materials

Six material families with researched subcategories.

  • Stainless SteelCompare austenitic, ferritic, martensitic, duplex and precipitation-hardening families before moving to a grade or product specification.
  • — AusteniticAustenitic stainless steels are chromium-containing grades whose nickel, manganese and/or nitrogen stabilize an austenitic matrix. They dominate general stainless fabrication because many grades combine corrosion resistance, ductility, weldability and broad product availability.
  • — FerriticFerritic stainless steels are chromium-based grades with a predominantly ferritic matrix. They are magnetic, generally resist chloride stress-corrosion cracking better than common austenitic grades, and serve cost-, oxidation- and forming-sensitive applications when their corrosion range is suitable.
  • — MartensiticMartensitic stainless steels are chromium steels with sufficient carbon and hardenability to transform during heat treatment. They are selected when hardness, edge retention, wear resistance or high strength is more important than the corrosion resistance and formability available from common austenitic grades.
  • — DuplexDuplex stainless steels are chromium-nickel grades engineered to contain substantial ferritic and austenitic phases after correct processing. They combine higher strength than common annealed austenitic grades with useful resistance to localized corrosion and chloride stress-corrosion cracking in suitable environments.
  • — Precipitation-hardeningPrecipitation-hardening stainless steels use a solution-treated structure followed by controlled aging to precipitate strengthening phases. They provide high strength with useful corrosion resistance, but properties, toughness, dimensional change and corrosion response depend directly on the selected aging condition.
  • Carbon & Structural SteelSeparate general carbon grades from structural, pressure-vessel, shipbuilding and pipeline specifications before comparing strength or price.
  • — Low-carbon steelLow-carbon steels contain comparatively little carbon and are widely used for formed, welded and machined products. “Mild steel” is an informal commercial description rather than a complete grade, so chemistry, product standard, strength class, surface and delivery condition still have to be ordered.
  • — Medium/high-carbonMedium- and high-carbon steels use increased carbon to support higher hardness, wear resistance and heat-treatment response. The same increase reduces weldability and forming margin, so grade chemistry, section size, prior condition and final heat treatment must be engineered together.
  • — Structural and HSLAStructural and high-strength low-alloy steels are product-specification grades developed for load-bearing members, plate, sheet and sections. They use strength class, chemistry/microalloying, rolling practice and toughness controls to deliver design properties with practical weldability.
  • — Pressure vessel steelPressure-vessel steels are plate and related products ordered for boilers, vessels, tanks and pressure equipment under material specifications coordinated with a construction code. Strength alone is insufficient: thickness, design temperature, notch toughness, heat treatment, weld procedure and examination determine acceptance.
  • — Shipbuilding steelShipbuilding steels are hull plate and section grades supplied under classification-society rules and approved manufacturing routes. Normal- and higher-strength grades combine strength level with toughness category, thickness, delivery condition and survey traceability for the intended hull location.
  • — Pipeline steelPipeline steels are line-pipe grades supplied as seamless or welded pipe under API, ISO or related project specifications. A grade such as X65 indicates a strength level within a system but does not define pipe process, PSL, delivery condition, dimensions, toughness, sour/offshore service, coating or inspection.
  • Alloy & Engineering SteelChoose the metallurgy around the component's controlling failure mode, section size and available heat-treatment route, then order the product form and verification that can prove that choice.
  • — Chromium-molybdenumChromium-molybdenum steels include machinery grades selected for hardenability and temper response as well as separate pressure/high-temperature product families. The shared alloy elements do not create one interchangeable material class.
  • — Nickel-chromium-molybdenumNickel-chromium-molybdenum steels are deep-hardening engineering steels selected when a large or highly stressed section needs a demanding strength-toughness balance. Cleanliness, forging reduction, quench access and inspection are part of the material decision.
  • — Case-hardeningCase-hardening steels pair a low-carbon core chemistry with carburizing, carbonitriding or a related surface-enrichment route to create a hard wear surface over a tougher core. The finished case profile is a process result, not a property guaranteed by the grade name.
  • — Bearing steelBearing steels are ordered around rolling-contact fatigue, cleanliness, carbide condition, surface integrity and heat-treatment response. A 52100-like chemistry without bearing-quality controls is not a bearing-material specification.
  • — Spring and heat-resistantThis navigation page contains two deliberately separate branches: spring steels selected for cyclic elastic duty and relaxation resistance, and heat-resistant engineering steels selected for creep, oxidation and pressure-code service. They share heat-treatment concepts, not one performance claim.
  • Aluminum & Aluminum AlloysNavigate 1xxx through 8xxx wrought series, then verify the exact registered alloy, temper and product specification.
  • — 1xxx Commercially Pure1xxx wrought aluminum contains 99% or more aluminum within the registered designation system. It is selected for conductivity, corrosion resistance, reflectivity and formability rather than high strength, with exact purity and temper controlling performance.
  • — 2xxx-Copper2xxx wrought alloys use copper as the principal alloying element and are generally heat treatable. They provide high specific strength and fatigue performance for aerospace and transport structures, while corrosion protection, fracture toughness and welding limitations need explicit review.
  • — 3xxx-Manganese3xxx wrought alloys use manganese as the principal addition and are non-heat-treatable. They combine moderate strength, formability and corrosion resistance for sheet, coil, heat-exchanger and packaging products, with final properties established mainly by cold-work temper.
  • — 5xxx-Magnesium5xxx wrought alloys use magnesium as the principal addition and are strengthened by solid solution and cold work rather than precipitation heat treatment. They offer useful weldability and corrosion resistance, but grade, temper and long-term temperature exposure must be checked for marine or sensitization-sensitive service.
  • — 6xxx-Magnesium-Silicon6xxx wrought alloys use magnesium and silicon to form a heat-treatable strengthening system. They are especially important for extrusions and combine moderate-to-high strength, corrosion resistance, weldability and surface-finish options; quench response and post-weld strength remain design considerations.
  • — 7xxx-Zinc7xxx wrought alloys use zinc, often with magnesium and copper, to obtain very high strength through precipitation heat treatment. They serve aerospace, tooling and high-performance structures but require deliberate temper selection for toughness, stress-corrosion resistance, fatigue and thick-section quench response.
  • — 8xxx Special-Purpose8xxx is the registered wrought-alloy series for principal alloying systems not represented by 2xxx through 7xxx. It includes widely used foil alloys and specialized electrical or low-density systems, so it is a designation bucket rather than one shared metallurgy or performance level.
  • Copper & Copper AlloysUse UNS families to separate conductivity, machinability, spring, wear, marine and high-strength systems.
  • — Pure & High-Copper AlloysPure and high-copper UNS families prioritize electrical/thermal conductivity, corrosion resistance and fabrication. Oxygen-bearing, oxygen-free and phosphorus-deoxidized grades differ in conductivity, hydrogen sensitivity, brazing/welding response and common product use.
  • — BrassBrasses are copper-zinc alloys spanning ductile cartridge brasses, free-machining grades, naval brasses and many cast families. Zinc level and additions such as lead, tin, aluminum or arsenic change forming, machining, strength and corrosion behavior, so the historical word “brass” is not a purchase specification.
  • — Phosphor & Tin BronzePhosphor and tin bronzes use tin for strength, wear and corrosion performance, often with phosphorus for deoxidation and spring properties in wrought products. Wrought spring strip and cast bearing bronze are distinct supply systems even when both are called tin bronze.
  • — Aluminum & Silicon BronzeAluminum bronzes and silicon bronzes are separate copper-alloy systems offering useful strength, corrosion resistance and wear or fabrication behavior. Aluminum bronzes can require phase and heat-treatment control, while silicon bronzes are valued for fabrication, casting and architectural color.
  • — Copper-NickelCopper-nickel alloys combine copper with nickel for seawater corrosion and biofouling-related performance, strength and fabrication. The common 90-10 and 70-30 systems differ in alloy content and service capability; successful use still depends on flow, commissioning, water chemistry, deposits and system design.
  • — High-Strength & High-Conductivity CopperHigh-strength high-conductivity copper alloys use precipitation or dispersion strengthening to retain more conductivity than many conventional high-strength copper alloys. Their useful balance depends on solution treatment, aging, cold work and service temperature, making temper and conductivity class essential purchase fields.
  • Galvanized & Coated SteelChoose the coating process first, then specify substrate, coating designation, surface treatment, fabrication and exposure.
  • — Batch Hot-Dip Galvanized SteelBatch hot-dip galvanizing immerses a cleaned, fabricated steel article in molten zinc so the coating forms after cutting and welding. It can cover edges and internal surfaces when design permits drainage and venting, but coating appearance and thickness follow fabricated-product standards rather than sheet G/Z designations.
  • — Continuous Galvanized SteelContinuous galvanized sheet is zinc-coated on a coil line before later slitting, forming and fabrication. Substrate grade, zinc coating designation, surface finish and chemical treatment are ordered together; exposed cut edges and later welds do not receive the same complete post-fabrication coverage as batch galvanizing.
  • — 55% Al-Zn / Aluzinc Coated Steel55% aluminum-zinc alloy-coated sheet is produced continuously and combines a distinct Al-Zn coating with a steel substrate. It differs from zinc galvanized sheet in coating chemistry, cut-edge behavior, heat reflectivity and compatible paint/processing practice; Galvalume is a trademarked name in some markets.
  • — Electrogalvanized SteelElectrogalvanized steel sheet receives zinc by electrolytic deposition, enabling controlled and potentially different coating masses on each surface with a smooth finish. It is distinct from continuous hot-dip galvanized sheet in process, coating designation, formability/paint route and typical corrosion-protection thickness.
  • — PPGI — Prepainted Galvanized SteelPPGI is a commercial system in which galvanized steel coil or sheet is pretreated and factory coated with primer and finish paint before forming. Performance depends on substrate grade, zinc coating mass, pretreatment, paint chemistry/thickness, color, forming severity, cut edges and exposure—not on the letters PPGI alone.
  • — PPGL — Prepainted Al-Zn Coated SteelPPGL uses a prepainted 55% Al-Zn or related Al-Zn metallic-coated substrate. It combines substrate, Al-Zn coating, pretreatment and paint layers, and should be selected by exposure, forming, cut-edge design and compatible paint system rather than unsupported universal life-multiplier claims.
  • Tool SteelA failure-mode-led guide to cold-work, hot-work, high-speed, shock-resisting and mold steels, with separate ordering evidence for each system.
  • — Cold-workCold-work tool steels serve forming and cutting tools operating near ambient temperature. Selection is a deliberate trade between abrasive wear, adhesive wear, plastic deformation, edge chipping, gross cracking and heat-treatment movement.
  • — Hot-workHot-work tool steels serve dies exposed to hot metal and repeated thermal cycles. They must balance hot strength and temper resistance with toughness, thermal-fatigue resistance and a cooling system that limits surface temperature gradients.
  • — High-speedHigh-speed steels are highly alloyed cutting-tool steels designed to retain cutting-edge hardness at elevated temperature. Their carbide system, heat treatment, grinding integrity, edge preparation and optional coating substrate condition form one tool system.
  • — Shock-resistingShock-resisting tool steels trade part of the wear ceiling for toughness under sudden impact, bending and localized stress concentration. Geometry, support and working hardness are as important as the S-series designation.
  • — Mold steelMold steels are purchased around block hardness uniformity, machinability, polish or texture response, corrosion exposure, weld repair and production volume. P20, 1.2738 and 420 mold-quality products represent different procurement systems.
  • Electrical SteelSelection separates directional transformer-core performance from rotating-machine isotropy and from semi-processed material that requires customer finishing treatment.
  • — Grain-orientedGrain-oriented electrical steel is processed to produce highly directional magnetic properties for transformer cores, so rolling direction, domain refinement, core construction and handling damage are central to procurement.
  • — Non-orientedNon-oriented electrical steel is processed for comparatively uniform in-plane magnetic behavior, serving rotating machines where flux direction changes and where loss, strength, punchability and gauge must be balanced.
  • — Semi-processedSemi-processed electrical steel is shipped before final magnetic properties are developed, transferring decarburizing or stress-relief annealing and part of the performance responsibility to the lamination manufacturer.
  • Cast IronFive procurement categories distinguish flake, spheroidal, compacted and temper-carbon graphite from carbide-rich white and alloyed irons.
  • — Gray ironGray cast iron contains flake graphite that gives excellent vibration damping, machinability and heat flow but creates stress concentration and low tensile ductility, making section-aware strength selection essential.
  • — Ductile ironDuctile iron uses spheroidal graphite to reduce crack-like stress concentration and provide useful yield strength and elongation, with matrix and heat treatment tailored from ferritic toughness to austempered strength.
  • — Compacted graphiteCompacted graphite iron uses vermicular graphite to bridge the thermal behavior of gray iron and the strength of ductile iron, but its narrow acceptable graphite morphology demands close process and microstructure control.
  • — Malleable ironMalleable iron is produced by prolonged heat treatment of white-iron castings to form temper carbon, providing ductility and machinability in relatively small, controlled-section fittings and hardware.
  • — White & alloyed ironWhite and alloyed cast irons intentionally retain carbide-rich structures for severe abrasion or alloy the matrix for corrosion and heat service, trading machinability and toughness for specialized surface life.
  • Nickel AlloysFive selection families separate pure-nickel alkali service, nickel-copper marine behavior, chromium-led oxidation resistance, chromium-molybdenum corrosion resistance and precipitation-strengthened superalloys.
  • — Pure nickelCommercially pure wrought nickel grades are selected for strong caustic resistance, controlled electrical or magnetic behavior and fabricability, with carbon level distinguishing general Nickel 200 from temperature-limited Nickel 201 use.
  • — Nickel-copperNickel-copper alloys such as Alloy 400 combine resistance to seawater, nonoxidizing salts and selected alkaline or reducing environments with useful toughness, while precipitation-hardened K-500 adds strength at different fabrication risk.
  • — Nickel-chromiumNickel-chromium and nickel-chromium-iron alloys use chromium for oxidation resistance and nickel for matrix stability, supporting furnace, heat-treatment and selected corrosive duties from Alloy 600 to Alloy 800-series systems.
  • — Ni-Cr-MoNickel-chromium-molybdenum alloys are corrosion-focused materials for aggressive mixed, reducing and chloride-bearing process streams, where alloy selection must follow full solution chemistry, redox state, temperature and fabrication history.
  • — Nickel superalloysNickel-base superalloys combine precipitation or solid-solution strengthening with oxidation resistance to carry sustained or cyclic loads at high temperature in turbines, aerospace engines, power equipment and demanding energy systems.
  • Titanium AlloysFour families separate commercially pure corrosion-led grades from alpha/near-alpha temperature service, alpha-beta general engineering alloys and metastable-beta high-strength systems.
  • — CP titaniumCommercially pure titanium Grades 1–4 are corrosion-led alpha materials whose oxygen content progressively raises strength while reducing ductility and formability, making grade and product specification inseparable.
  • — Alpha / near-alphaAlpha and near-alpha titanium alloys retain microstructural stability and creep resistance above the practical range of many alpha-beta alloys, with weldability and oxidation exposure controlling engine and hot-structure use.
  • — Alpha-betaAlpha-beta titanium alloys combine alpha stability with beta-enabled processing and heat-treatment response; Ti-6Al-4V dominates, but ELI chemistry, section response and microstructure change fatigue and toughness acceptance.
  • — Beta titaniumMetastable-beta titanium alloys retain beta after solution treatment and develop high strength through aging, enabling complex forming or high-strength forgings but demanding tight heat-treatment and section-uniformity control.
  • Magnesium AlloysThe taxonomy separates product route from AZ, ZK and rare-earth chemistry systems so buyers can specify both alloy identity and manufacturing acceptance.
  • — Wrought magnesiumWrought magnesium sheet, extrusion and forgings develop route-dependent texture and anisotropy, so temper, grain direction, formability and corrosion finish must accompany the alloy designation.
  • — Cast magnesiumCast magnesium procurement must distinguish sand, permanent-mold and high-pressure die casting because fill, porosity, heat treatment and attainable inspection differ even for related chemistries.
  • — Mg-Al-Zn alloysAZ magnesium alloys use aluminum and zinc for castability or wrought strength, but AZ31, AZ80 and AZ91 belong to different product routes and temperature capabilities.
  • — Mg-Zn-Zr alloysZK alloys combine zinc strengthening with zirconium grain refinement for high-strength wrought products, while forgeability, texture and stress-corrosion behavior limit direct substitution for AZ systems.
  • — Rare-earth magnesiumRare-earth magnesium alloys use yttrium, neodymium or other additions to improve creep, ignition or corrosion behavior for hotter and more demanding service, but grade-specific casting and heat treatment remain critical.
  • Cobalt AlloysFour procurement groups separate Co-Cr bulk alloys, wear-resistant deposits and castings, cobalt-base superalloys and cobalt-bonded cemented carbides.
  • — Co-CrCobalt-chromium alloys rely on a passive chromium-rich surface and route-dependent carbide structure for corrosion, wear and biomedical service, with cast, wrought and additively manufactured conditions requiring separate qualification.
  • — Wear-resistant cobaltWear-resistant cobalt alloys are selected as cast parts, rods or hardfacing deposits for galling, erosion and hot wear; deposit dilution, cracking tolerance and finish geometry can control service more than nominal filler chemistry.
  • — Cobalt superalloysCobalt-base superalloys combine solid-solution and carbide strengthening with hot-corrosion resistance for combustor and furnace components, requiring product-route, grain and heat-treatment controls rather than a generic temperature rating.
  • — Co-bonded hardmetalsCobalt-bonded hardmetals use a ductile cobalt binder around tungsten-carbide or related hard particles; carbide size, binder fraction, porosity and sintering route define grade behavior beyond nominal WC-Co chemistry.
  • Zinc AlloysThe directory separates Zamak, higher-aluminum ZA, wrought zinc and sheet/strip procurement while excluding galvanized steel from the base-alloy taxonomy.
  • — ZamakZamak alloys are high-purity zinc-aluminum-magnesium(-copper) systems optimized for pressure die casting, with copper level, impurity control, creep and post-cast dimensional aging guiding grade choice.
  • — ZA alloysZinc-aluminum ZA alloys contain more aluminum than Zamak and serve pressure, permanent-mold, sand or continuous casting, with ZA-8, ZA-12 and ZA-27 requiring different process and section controls.
  • — Wrought zincWrought zinc alloys are rolled, extruded or drawn systems selected for formability, sacrificial electrochemical behavior or specialized mechanical products, and must be ordered by product form rather than casting designation.
  • — Zinc sheetZinc sheet and strip are solid zinc-alloy rolled products for roofing, façade, battery and formed applications; they are not galvanized steel, whose steel substrate and coating mass govern a different product system.
  • Refractory MetalsFour element-led procurement pages separate very different density, corrosion, ductility and high-temperature design constraints.
  • — TungstenTungsten products range from brittle high-purity sheet and wire to machinable nickel-iron or nickel-copper heavy alloys and W-Re thermomechanical systems; density and melting point alone do not define interchangeability.
  • — MolybdenumMolybdenum combines high-temperature stiffness with lower density than tungsten, while TZM and lanthanum-doped systems improve recrystallization or creep behavior only when processing and grain structure are controlled.
  • — TantalumTantalum is selected for exceptional resistance to many chemical media and vacuum high-temperature service, while Ta-W alloys add strength at the cost of forming margin and higher fabrication control.
  • — NiobiumNiobium products span high-purity superconducting sheet and tube to oxidation-sensitive C-103 aerospace alloy, so purity, residual resistance or high-temperature coating requirements belong to different purchase paths.
  • Metal PowdersSix chemistry-specific guides connect base-alloy behavior to powder production, handling and consolidation without claiming wrought-equivalent properties.
  • — Ferrous powdersIron and steel powders range from sponge and water-atomized press-and-sinter feedstock to prealloyed AM powder; compressibility, green strength and alloying route distinguish them.
  • — Stainless powdersStainless steel powders require chromium-bearing chemistry plus controlled oxygen, nitrogen and carbon because atomization and reuse can change oxide films, flow and consolidated corrosion performance.
  • — Aluminum powdersAluminum alloy powders combine persistent oxide films, low density and combustible dust risk; PSD, satellites and moisture control affect spreading, fusion and safe handling.
  • — Titanium powdersTitanium alloy powders demand tight oxygen, nitrogen and hydrogen control, with plasma or gas atomization, handling and reuse influencing interstitial pickup and fatigue-critical defects.
  • — Nickel powdersNickel superalloy powders preserve complex precipitation chemistry while segregation, inclusions, reused-powder drift and process cracking determine whether a nominal alloy can produce qualified high-temperature parts.
  • — Copper powdersCopper and copper-alloy powders combine oxidation sensitivity with high thermal conductivity and laser reflectivity, requiring process-specific purity, morphology and consolidation controls.

Grade guides

Authority pages for commonly specified alloy and steel grades.

  • 304 Stainless Steel304 is the benchmark austenitic stainless steel for equipment, architectural trim, food-contact fabrication, and general industrial parts. It combines broad availability, formability, weldability, and useful corrosion resistance, but chloride exposure can justify a molybdenum-bearing grade.
  • 304L Stainless Steel304L limits carbon to reduce sensitization risk around welds and is widely specified for tanks, sheet assemblies, pipework, and general fabricated equipment. Its corrosion envelope remains similar to 304, so the L suffix does not turn it into a chloride-service or marine grade.
  • 316 Stainless Steel316 adds molybdenum to the chromium-nickel austenitic base, improving resistance to pitting and crevice corrosion relative to 304 in many chloride-bearing environments. It is not automatically suitable for seawater, and temperature, chloride concentration, deposits, crevices, and cleaning practice remain decisive.
  • 316L Stainless Steel316L combines the localized-corrosion benefit of molybdenum with a low carbon limit intended to reduce sensitization risk in welded assemblies. It is a common specification for process, pharmaceutical, food, coastal, and hygienic equipment, but it still requires environmental and surface-condition review.
  • 321 Stainless Steel321 is a titanium-stabilized austenitic stainless selected where welded components face temperatures that can promote chromium-carbide precipitation. It is associated with exhaust, thermal-processing, and aerospace fabrications, while room-temperature chloride resistance remains broadly comparable to 304 rather than 316.
  • 347 Stainless Steel347 uses niobium stabilization to control chromium-carbide precipitation during welding and thermal exposure. It is commonly evaluated for pressure, refinery, power-generation, and aerospace components where high-temperature service matters more than the extra chloride resistance of molybdenum-bearing grades.
  • 430 Stainless Steel430 is a nickel-lean ferritic stainless used for appliances, interior trim, equipment panels, and other sheet applications where moderate corrosion resistance, magnetic response, and cost control are valued. It is less formable and generally less corrosion-resistant than 304 in demanding service.
  • 409 Stainless Steel409 is a low-alloy ferritic stainless engineered for oxidation resistance, fabrication, and cost-sensitive exhaust applications. It can develop visible surface rust in wet atmospheric exposure while continuing to provide useful service, so it is not selected where a bright decorative appearance is mandatory.
  • 2205 Duplex Stainless Steel2205 duplex stainless combines ferritic and austenitic phases to deliver substantially higher strength than common 300-series grades and improved resistance to chloride stress-corrosion cracking. Welding and heat treatment must preserve phase balance, making qualified fabrication essential.
  • 17-4 PH Stainless Steel17-4 PH is a martensitic precipitation-hardening stainless strengthened by solution treatment and aging. It is widely used for shafts, valves, fasteners, aerospace parts, and tooling where strength exceeds that of annealed austenitic grades, but properties and corrosion behavior depend strongly on heat-treatment condition.
  • 201 Stainless Steel201 stainless steel replaces part of the nickel used in conventional chromium-nickel austenitic grades with manganese and nitrogen. It offers useful strength, formability, and atmospheric corrosion resistance for controlled environments, but it is not a universal low-cost substitute for 304 in chloride, hygienic, or heavily welded service.
  • 439 Stainless Steel439 is a low-carbon, titanium-stabilized ferritic stainless steel developed to improve weld durability and elevated-temperature performance over basic 430-type material. It is widely considered for automotive exhaust and heat-transfer components, while formability, weld procedure, surface condition, and the exact product specification remain purchase-critical.
  • 441 Stainless Steel441 is a low-carbon, dual-stabilized ferritic stainless steel using titanium and niobium to support weld stability, creep resistance, and thermal-fatigue performance. It is common in exhaust and high-temperature fabricated components, but its useful service envelope depends on product thickness, forming route, weld quality, and the actual thermal atmosphere.
  • 410 Stainless Steel410 is a martensitic stainless steel that can be hardened and tempered to balance strength, hardness, and toughness. Its corrosion resistance is useful in mild environments but generally below austenitic grades; successful procurement therefore requires the exact product form, heat-treatment condition, hardness or strength target, section size, and machining allowance.
  • 420 Stainless Steel420 denotes a higher-carbon martensitic stainless family capable of substantially greater hardness than 410 after quenching and tempering. Carbon limits and commercial variants differ, so an order must identify the exact UNS or product specification, required hardness, heat-treatment route, section size, finish, and corrosion expectations rather than relying on the name 420 alone.
  • 431 Stainless Steel431 is a chromium-nickel martensitic stainless steel selected for high strength, toughness, and better corrosion resistance than basic 410-type grades in suitable environments. It is supplied and used in specific hardened-and-tempered conditions, so section size, mechanical target, tempering temperature, straightness, machining sequence, and final surface condition must be controlled.
  • 440C Stainless Steel440C is the high-carbon member of the 440 martensitic stainless family and is used where high hardness, wear resistance, and dimensional control are required together with moderate corrosion resistance. Its carbide population, heat-treatment response, retained austenite, grinding practice, and final passivation strongly influence performance, so condition-specific procurement is essential.
  • 2101 Lean Duplex Stainless Steel2101 lean duplex stainless uses chromium, manganese, and nitrogen with relatively low nickel and molybdenum to deliver high strength and useful corrosion resistance. It can compete with 304L or 316L in selected tank, structural, and process duties, but substitution requires verification of pitting, crevice, weld, low-temperature, and product-standard requirements.
  • 2304 Duplex Stainless Steel2304 is a chromium-nickel-nitrogen duplex stainless steel with little molybdenum, providing roughly twice the yield strength of common annealed austenitic grades and useful stress-corrosion resistance. It is selected for verified structural, storage, water, and process environments, while pitting demand, weld procedure, phase balance, impact requirements, and product form control the decision.
  • 2507 Super Duplex Stainless Steel2507 super duplex stainless combines approximately 25% chromium with molybdenum and nitrogen to provide very high strength and high resistance to chloride pitting, crevice corrosion, and stress-corrosion cracking. It is used in demanding offshore, desalination, chemical, and pulp systems, but welding, phase balance, temperature limits, sour-service rules, and exact product standards remain decisive.
  • 15-5 PH Stainless Steel15-5 PH is a chromium-nickel-copper precipitation-hardening stainless steel developed for high strength, hardness, good forgeability, and improved transverse toughness compared with conventional 17-4 PH processing. Properties depend on solution treatment, aging condition, product form, section size, and orientation, so the condition must be part of every drawing, certificate, and acceptance test.
  • 17-7 PH Stainless Steel17-7 PH is a chromium-nickel-aluminum semi-austenitic precipitation-hardening stainless steel supplied in formable austenitic conditions and transformed and aged to develop high strength. Condition A, TH, RH, and cold-worked routes are not interchangeable; product form, transformation treatment, aging cycle, dimensional change, spring direction, and final properties must all be specified.
  • SAE 1008 Low-Carbon Steel for Cold-Rolled SheetSAE 1008 identifies a chemistry range in SAE J403. It can be screened for forming-oriented cold-rolled sheet, but it does not establish drawing quality, mechanical properties, surface class or delivery condition; those controls belong in the finished-sheet product specification and order.
  • SAE 1010 Low-Carbon Steel for Cold-Rolled SheetSAE 1010 identifies its own chemistry range in SAE J403. It may be considered for blanked, roll-formed or general fabricated sheet, but it does not establish strength, hardness, surface or dimensional acceptance without a finished-product specification.
  • ASTM A36 Carbon Structural SteelASTM A36/A36M is a product specification for carbon structural steel rather than a universal chemistry-only alloy designation. Product form, thickness, the general requirements of ASTM A6/A6M, and ordered supplementary requirements control acceptance.
  • ASTM A516 Grade 70 Pressure Vessel SteelASTM A516/A516M Grade 70 is a pressure-vessel plate specification with strength, chemistry, heat-treatment, testing, and supplementary requirements tied to plate thickness and the construction code. It should not be purchased as generic Grade 70 plate.
  • ASTM A572 Grade 50 HSLA Structural SteelASTM A572/A572M Grade 50 is a high-strength low-alloy structural steel specification using controlled microalloying. It offers higher minimum yield strength than A36, but toughness, weldability, product availability, and substitution remain project-specific.
  • ASTM A588 Weathering Structural SteelASTM A588/A588M covers high-strength low-alloy structural steel with improved atmospheric corrosion resistance. Successful unpainted use depends on exposure, wet-dry cycling, drainage, detailing, contaminants, and local design guidance—not the grade name alone.
  • SAE/AISI 1018 Low-Carbon SteelSAE 1018 identifies a low-carbon steel chemistry, not a single guaranteed strength condition. Hot-rolled, cold-finished, normalized, forged, drawn, and machined products can have different properties, dimensions, surface quality, and residual stress.
  • SAE/AISI 1020 Low-Carbon SteelSAE 1020 is a low-carbon chemistry designation whose mechanical behavior depends on product form, section size, cold work, heat treatment, and manufacturing route. It should be paired with a product specification and ordered condition.
  • SAE/AISI 1045 Medium-Carbon SteelSAE 1045 is a medium-carbon steel chemistry used for shafts, pins, gears, and machinery parts. Normalized, annealed, cold-finished, induction-hardened, and quenched-and-tempered conditions have substantially different strength, hardness, toughness, and machinability.
  • SAE/AISI 4140 Chromium-Molybdenum SteelSAE 4140 is a chromium-molybdenum alloy-steel chemistry with greater hardenability than plain medium-carbon steel. Final properties depend on section size, austenitizing, quench severity, tempering, cleanliness, and product specification.
  • 5052 Aluminum Alloy5052 is an aluminum-magnesium wrought alloy widely supplied as sheet, plate, and coil. Strength comes mainly from strain hardening, so H32, H34, annealed, and other tempers must not be treated as the same material condition.
  • 5083 Marine Aluminum Alloy5083 is a high-magnesium aluminum alloy used in marine, transportation, cryogenic, and welded plate applications. Marine performance is tied to temper and product controls such as H116 or H321, not to the 5083 designation alone.
  • 6061 Aluminum Alloy6061 is a heat-treatable aluminum-magnesium-silicon alloy used across structural, transportation, marine, and machined components. T6, T651, T6511, annealed, and as-fabricated weld zones have different properties and dimensional behavior.
  • 6063 Architectural Aluminum Alloy6063 is a heat-treatable 6xxx alloy strongly associated with architectural and general-purpose extrusions. T5 and T6 strength, wall thickness, profile geometry, dimensional tolerance, surface quality, and anodizing requirements must be ordered together.
  • ASTM A53 Grade B Steel PipeASTM A53/A53M Grade B is a steel-pipe product designation, not a generic carbon-steel chemistry. A compliant order must identify Type E electric-resistance-welded or Type S seamless construction, black or hot-dip zinc-coated finish, NPS/DN, schedule or wall, length, ends, tests and the applicable piping or project code.
  • ASTM A106 Grade B Seamless Steel PipeASTM A106/A106M Grade B is a seamless carbon-steel pipe product specification for high-temperature service. It does not cover welded pipe, and the grade alone does not establish design pressure, allowable stress, corrosion allowance, low-temperature toughness, sour-service suitability, dimensions, ends or supplementary tests.
  • 8079 Aluminum Foil8079 is a registered wrought aluminum alloy explicitly listed in ASTM B479 for annealed foil when the ordered product falls within that standard's scope. Its alloy designation is not a finished-package claim: the RFQ needs the exact temper, thickness, width, surface side, pinhole and wettability requirements, cleanliness, winding, splices, inspection, protective packing and the validated laminate, forming or end-use compliance criteria.
  • 1235 Aluminum Foil1235 is a registered wrought aluminum alloy explicitly listed in ASTM B479 for annealed foil when the ordered product falls within that standard's scope. Alloy identity does not define the finished package or laminate: the RFQ must specify temper, thickness, width, surface side, pinhole and wettability limits, cleanliness, winding, splices, inspection, packing and any end-use compliance or converter validation.
  • 8011 Aluminum Foil8011 is a registered wrought aluminum alloy widely supplied as foil, but alloy identity alone does not define a packaging product. The order must add exact temper, thickness, width, surface side, pinhole and wettability criteria, tensile or burst requirements, cleanliness, food-contact or pharmaceutical compliance, winding, splices and packing.
  • 8021 Aluminum Foil8021 is a registered wrought aluminum alloy used in high-barrier foil applications, often in soft tempers for forming and pharmaceutical laminate systems. It is not explicitly named in ASTM B479's listed alloy examples, so procurement should use the registered chemistry together with the applicable EN 546, ISO 7271, national or customer foil specification and end-use compliance requirements.
  • DX51D+Z Galvanized SteelDX51D+Z is an EN 10346 designation for continuously hot-dip zinc-coated low-carbon flat product intended for cold forming. DX51D identifies the substrate/forming designation and +Z identifies zinc coating, but neither defines coating mass, surface quality, finish, treatment, thickness, tolerance, oiling, passivation, spangle or final forming performance without the remaining order details.
  • SGCC Galvanized SteelSGCC is a JIS G 3302 designation for commercial-quality hot-dip zinc-coated steel sheet and strip. It is not a universal name for all galvanized coil and does not by itself define coating mass, chromate-free treatment, oiling, spangle, skin pass, surface quality, dimensional tolerance, mechanical properties or suitability for a specific formed part.
  • API 5L X70 Line PipeAPI 5L X70 is a line pipe strength designation under API Specification 5L, not a complete purchasing description or an automatic substitution. A usable order identifies PSL, pipe type, dimensions, delivery condition, service annexes, nondestructive examination, hydrotest, marking and traceability.
  • G60 Galvanized CoatingG60 is the ASTM A653/A653M inch-pound designation for a minimum 0.60 oz/ft² total coating weight on both sides of continuously hot-dip galvanized sheet. It does not specify how zinc is distributed side-to-side, the substrate grade, surface treatment, forming quality or corrosion life.
  • G90 Galvanized CoatingG90 is the ASTM A653/A653M inch-pound designation for a minimum 0.90 oz/ft² total zinc coating weight on both sides. The heavier class can provide more zinc reserve than G60 under comparable conditions, but it is not a universal corrosion-life promise and does not replace exposure, substrate, surface or fabrication requirements.
  • Z275 Galvanized CoatingZ275 under EN 10346 specifies a minimum 275 g/m² total zinc coating mass on both sides of continuously hot-dip coated flat product. The designation belongs inside an EN order with its substrate grade, surface quality, treatment and inspection rules; the mass number alone does not prove full equivalence to an ASTM product.
  • API 5L Grade B Line PipeAPI 5L Grade B is a lower-strength tier relative to X52 and X65 in the API 5L line-pipe family. It can suit project-defined gathering, distribution or utility pipeline duty, but the current edition, PSL, pipe type, dimensions, design code, medium and supplementary requirements—not the grade name—establish acceptance.
  • API 5L X52 Line PipeAPI 5L X52 is an X-grade line-pipe designation often evaluated for transmission and gathering projects seeking more specified strength than Grade B while retaining a project-qualified welding and forming route. A complete order still requires the current API 5L edition, PSL, pipe type, dimensions, delivery condition, toughness and service annexes.
  • API 5L X65 Line PipeAPI 5L X65 is a higher-strength line-pipe grade than X52 and Grade B. Designers may evaluate it for transmission duty and potential wall or mass efficiency, but no reduction is automatic: the pipeline code calculation, dimensional availability, PSL, toughness, weldability, field bending and fracture-control requirements govern.
  • 3003 Aluminum Alloy3003 is a registered wrought aluminum alloy commonly supplied as sheet and coil. Alloy number alone is incomplete buying information: temper, product specification, thickness, width, tolerances, surface, fabrication route, tests and certificate must be stated. Property and forming response vary with temper and product form.

Applications

Material-selection and procurement guides organized by operating application.

  • Steel for Airport ConstructionAirport procurement is a system-by-system exercise: structural demand, fire strategy, public-area finish, drainage chemistry, maintainability, local code, and inspection determine the appropriate steel product.
  • Metals for ShipbuildingShip metal selection follows vessel class, flag and class rules, structural zone, seawater exposure, cargo, temperature, welding procedure, fire safety, and inspection—not a universal marine-grade list.
  • Steel for Ports and Marine InfrastructurePort steel packages must separate atmospheric, splash, tidal, immersed, buried, and abrasion zones, then align structural design, coating, corrosion allowance, inspection, and replaceability.
  • Steel for Oil, Gas, and Pipeline ProjectsOil and gas steel procurement begins with fluid composition, pressure, temperature, fracture control, sour-service risk, corrosion management, joining, inspection, and the governing piping or pipeline code.
  • Metals for Food Processing EquipmentFood-equipment metal selection combines hygienic design, product chemistry, cleaning regime, temperature, surface finish, drainability, welding quality, regulatory documentation, and maintainability.
  • Metals for Solar Energy SystemsSolar metal procurement connects site loads, foundation and roof interfaces, structural stiffness, atmospheric corrosion, galvanic compatibility, grounding and twenty-plus-year maintenance access to a traceable racking and enclosure package.
  • Metals for Water Treatment and DesalinationWater-treatment metal selection begins with feed and concentrate chemistry, chlorides, oxidants, pressure, temperature, velocity, stagnation, crevices, cleaning and dissimilar-metal interfaces—not a generic stainless grade list.
  • Metals for Pressure VesselsPressure-vessel procurement ties the construction code, design conditions, allowable stress, material specification, thickness, toughness, corrosion, forming, welding, heat treatment, NDE and certification into one controlled package.
  • Metals for HVAC SystemsHVAC metal selection depends on air chemistry, moisture, pressure class, leakage, fire and hygiene requirements, external exposure, insulation and cleaning—not duct gauge alone.
  • Steel for Warehouses and Logistics BuildingsWarehouse steel procurement coordinates grid, clear height, storage and automation loads, wind and seismic actions, fire strategy, primary and secondary members, envelope, fabrication, erection and expansion planning.
  • Metals for Roofing and CladdingRoofing and cladding procurement separates structural substrate, metallic coating, organic paint system, profile, fasteners, joints, drainage, environment and warranty instead of buying by color or paint name alone.
  • Aluminum-Foil Moisture Barriers for Gas-Detector ToolboxesA gas-detector toolbox moisture barrier is a qualified package system: aluminum-foil laminate, seals, desiccant, humidity indicator, puncture protection, clean packing and verified water-vapour transmission—not loose foil wrapped around an instrument.
  • Steel for Bridges and Highway StructuresBridge-steel procurement must connect structural analysis, fatigue category, fracture toughness, weldability, corrosion exposure, drainage detailing, fabrication geometry and owner inspection requirements—not merely select a nominal grade.
  • Metals for Petrochemical PlantsPetrochemical material selection starts with the complete process stream, contaminants, pressure-temperature envelope, corrosion mechanisms, shutdown conditions, welding and inspection—not a universal stainless or carbon-steel preference.
  • Stainless Steel for Pharmaceutical EquipmentPharmaceutical stainless procurement joins product-contact risk, cleanability, surface finish, drainage, welding, passivation, cleaning chemistry and validation into a documented hygienic boundary.
  • Metals for Data CentersData-center metal packages must support rapid structural delivery, dense MEP coordination, continuous cooling, water chemistry, condensation control, fire separation, maintainability and future expansion.
  • Steel for Mining and Mineral-Processing EquipmentMining-equipment steel selection must separate structural loading, impact, abrasion, corrosion, fatigue, weld repair and replaceable wear parts instead of treating hardness as the only purchasing variable.
  • Metals for Electrical EnclosuresElectrical-enclosure metal selection must satisfy the declared enclosure or IP performance, structural stiffness, corrosion environment, heat management, grounding, fabrication and gasketed interface as one tested assembly.
  • Metals for LNG and Cryogenic SystemsCryogenic procurement must connect minimum design metal temperature, toughness, thermal contraction, pressure containment, welding, insulation interfaces and emergency exposure. A familiar ambient-temperature material name is not evidence of low-temperature suitability.
  • Metals for Hydrogen SystemsHydrogen-service procurement requires a documented compatibility and integrity basis for pressure, gas purity, cycling, temperature, welds, leakage and inspection. Material selection cannot rely on conventional gas-service assumptions alone.
  • Metals for Heat ExchangersHeat-exchanger metal selection is governed by both sides of the exchanger: fluid chemistry, chlorides, pressure, temperature, velocity, fouling, crevices, thermal cycling and fabrication. Selecting tube or plate by grade name alone can create a hidden failure point.
  • Steel for Industrial BoilersBoiler procurement must be driven by the governing construction code, pressure-temperature design, material specification, allowable stress, thickness, welding, heat treatment, examination and certification. A nominal plate grade is not a boiler package.
  • Metals for Pumps and ValvesPump and valve material selection depends on the actual fluid, pressure, temperature, solids, velocity, cavitation, corrosion, erosion, wear, sealing and maintenance route. A piping grade cannot simply be copied to every wetted component.
  • Steel for Wind Energy SystemsWind-energy metal packages connect design loads, fatigue, corrosion, foundations, tower interfaces, transport constraints, bolting, welding, coating and field assembly. Strength grade alone cannot qualify a component for a wind project.
  • Metals for Automotive ManufacturingAutomotive metal sourcing is a controlled, multi-material process. Product form, alloy or steel grade, temper, coating, surface, forming route, joining, corrosion performance, dimensional capability and approved qualification cannot be replaced by a generic material name.
  • Metals for Electric VehiclesEV metal selection connects vehicle structure, battery enclosure, thermal paths, electrical interfaces, crash performance, corrosion, fire-safety integration, repairability and traceability. The chemistry and approved pack architecture govern the component specification; metal stock alone does not certify a battery system.
  • Aluminum for Busbars and TransformersElectrical aluminum procurement must define conductor designation, temper, cross-section, conductivity or resistivity requirement, joints, plating, bending, insulation interfaces, heat rise and applicable electrical equipment rules. A sheet or strip label alone is not a busbar specification.
  • Aluminum Foil for Cable ShieldingCable-shielding foil is a functional component of a qualified cable construction. Specify alloy, temper, thickness, width, coating or laminate, pinhole control, surface condition, winding, splice, electrical performance and compatibility with the insulation and cable design; commodity foil is not interchangeable by thickness alone.
  • Aluminum Foil for Pharmaceutical PackagingPharmaceutical packaging foil is one component in a validated package system. Foil alloy and gauge, laminate, coating, printing, sealing, forming, barrier performance, defects, clean handling and market-specific compliance must be defined from the finished pack—not inferred from a foil description alone.
  • Aluminum Foil for Food PackagingFood-packaging foil must be specified as part of the finished food-contact article. Food type, time and temperature, foil and laminate construction, inks, adhesives, coatings, sealing, migration/compliance basis and local market requirements all matter; a foil roll is not a food-contact approval by itself.
  • Aluminum Foil for Moisture-Barrier PackagingA moisture-barrier pack is specified by the complete laminate, seal integrity, defects, product moisture sensitivity, storage climate, handling damage and test method. Foil gauge alone does not establish water-vapour protection after converting, creasing or sealing.
  • Aluminum Foil for Export Preservation PackagingExport preservation packaging must protect the specific product through its transport route, storage duration and destination climate. Aluminum foil is commonly used in multilayer barriers, but corrosion protection also depends on cleanliness, desiccant strategy, sealing, void volume, handling, outer pack and inspection—not a generic foil grade.
  • Steel for Railway and Metro SystemsRail and metro procurement must follow the project owner’s track, bridge, station and systems requirements. Loads, fatigue, vibration, clearances, fire, corrosion, fabrication, inspection and access cannot be established from a steel grade alone.
  • Steel for Offshore PlatformsOffshore steel selection connects waves, wind, fatigue, corrosion, splash-zone exposure, cathodic protection, welding, inspection, access and repair. Material certificates do not replace platform design, corrosion-management or structural-integrity requirements.
  • Metals for Power GenerationPower-generation metal procurement is governed by component duty, pressure, temperature, corrosion, thermal cycling, fabrication and code requirements. A plate, pipe or stainless grade is not interchangeable across boiler, turbine, cooling-water or structural service without project review.
  • Steel for Stadiums and Exhibition CentersLarge-span venues require engineered control of primary structure, connections, long-span behavior, erection, architectural exposure, corrosion protection, fire strategy, roofing interfaces and maintenance. Steel products must be ordered against approved drawings and specifications, not visual intent alone.
  • Metals for Hospitals and Clean BuildingsHospital and clean-building metal selection must be tied to the approved facility, hygiene, cleanability, fire, corrosion and maintenance requirements. Stainless grade alone does not validate a cleaning procedure or a finished healthcare environment.
  • Metals for Battery Energy Storage SystemsBattery-system metal procurement must support the approved enclosure, structural, thermal, electrical and safety design. Metal stock does not certify an energy-storage system or replace validation of the complete assembly.
  • Steel for Agricultural MachineryAgricultural machinery steel must be selected for loads, forming, welding, abrasion, corrosion, coating, repair and seasonal service. A higher-strength grade alone does not prove fatigue life, joint performance or field durability.
  • Metals for Nuclear Power FacilitiesNuclear-facility metal procurement follows the approved design authority, safety classification, qualification route, configuration control and regulatory framework. Commercial steel, stainless or aluminum products are not nuclear-qualified or safety-system-approved merely because a mill certificate is supplied.
  • Metals for Aerospace ManufacturingAerospace metal procurement must conform to approved design data, material specification, condition, lot traceability, special-process controls and inspection route. A recognized alloy or mill certificate does not by itself authorize flight hardware, replacement parts or spacecraft use.
  • Stainless Steel for Coastal ArchitectureCoastal stainless selection is an exposure, detailing, finish, fabrication and maintenance decision—not a grade-name shortcut. Chloride deposition, distance and orientation to the sea, sheltering, drainage, crevices, dissimilar-metal contact, surface finish, weld restoration and cleaning plan must be reviewed with the project engineer.
  • Galvanized Pipe for Water and Fire-Protection SystemsGalvanized pipe is not universally accepted for potable-water or fire-protection systems. The local code, authority having jurisdiction, approved system listing and project specification must accept the base pipe, galvanizing route, dimensions, joining, pressure tests and water chemistry; a zinc coating or mill certificate does not establish system approval.
  • Aluminum-Foil Moisture Barriers for Toolboxes and InstrumentsAluminum foil can be one layer in a moisture-barrier laminate, but foil gauge alone is not a barrier specification. The complete system includes alloy/temper, laminate structure, pinhole control, puncture and flex resistance, seam and closure sealing, desiccant sizing, humidity indication, handling, storage duration and validation against the real package and climate.

Standards & grade systems

Designation systems and families used to interpret specifications.

  • API 5L Grade B and X42 Line PipeAPI 5L Grade B and X42 are line-pipe designations that must be ordered with the applicable product specification, PSL, manufacturing route, dimensions, delivery condition and service requirements. The grade name alone is not a complete purchase description.
  • API 5L X52–X65 Line Pipe Selection SystemAPI 5L X52–X65 is a selection range, not a group of interchangeable commodity labels. Define PSL, type, dimensions, delivery condition, service annexes, NDE, hydrotest and documentation.
  • Normal-Strength Shipbuilding Steel GradesA/B/D/E notation is used within normal-strength hull structural steel systems. The letter relates to toughness and testing context under the governing rules; it does not by itself define a universal substitute or a finished purchasing specification.
  • AH36, DH36 and EH36 Shipbuilding Steel SystemAH36, DH36 and EH36 belong to a 36-strength hull-steel group but differ in toughness designation and approved condition context. Their selection must be tied to the hull member, design temperature, thickness, delivery condition and class approval.
  • Higher-Strength Shipbuilding Steel SeriesHigher-strength hull steel designations are controlled by strength family, toughness class, thickness, delivery condition and classification approval. Selecting a higher strength notation does not itself prove weld procedure, fracture performance or suitability for every hull member.
  • UNS Unified Numbering System for Metals and AlloysA UNS number is a composition-family identifier used to correlate metal and alloy designations. It helps records and cross-references, but it does not state product form, dimensions, delivery condition, properties, tests or purchase acceptance.
  • How to Read ASTM Specification Designations for Metal ProcurementAn ASTM designation identifies a standards document and its revision context—not necessarily a metal grade. Buyers must distinguish specifications from test methods, practices and guides, then state the product grade, unit system and supplementary requirements separately.
  • SAE Carbon and Alloy Steel Numbering SystemSAE four-digit steel numbers organize selected carbon and alloy steel chemistry families. They are useful material identifiers, but they do not by themselves define product form, hardenability, heat treatment, mechanical properties, surface condition or inspection acceptance.
  • EN 10027 Steel Names and Material NumbersEN 10027 separates symbolic steel names from numerical material numbers. Both help identify a steel, but neither replaces the EN product standard, delivery condition, thickness-dependent properties, inspection document or project requirements needed for an order.
  • JIS Steel Designation System for Product ProcurementJIS steel symbols must be read inside the Japanese product standard that defines them. A familiar prefix or number may suggest product and grade context, but it cannot establish form, dimensions, condition, properties or acceptance outside that document.
  • GB/T 221 Steel Designation SystemGB/T 221 establishes notation rules for Chinese iron and steel designations. It explains how symbols, element letters and numerical values are assembled, but the resulting name must still be tied to the applicable product standard, condition and acceptance requirements.
  • ISO Steel Classification by Chemical CompositionISO 4948-1 classifies steels by chemical composition into unalloyed and alloyed groupings. It is a classification framework for technical communication, not a product specification, grade equivalence table or independent basis for ordering steel.
  • Stainless Steel Cross-Standard Designation BoundariesStainless designations from ASTM/UNS, EN, JIS, GB and ISO can look closely related, but matching chemistry families do not establish product or service equivalence. A defensible comparison must preserve product form, specification, condition, properties and acceptance testing.
  • Aluminum Association Alloy Numbering SystemAluminum Association registrations provide internationally recognized identifiers for wrought and cast aluminum alloys. The wrought four-digit series and casting designation family organize alloy identity, but neither specifies temper, product form, dimensions or finished-product acceptance.
  • Aluminum Temper Designations for Product ProcurementAn aluminum temper designation records the processing condition applied after alloy production. F, O, H, W and T families distinguish fabrication, annealing, strain hardening, solution heat treatment and thermally treated conditions, but exact properties remain product- and thickness-dependent.
  • ASTM A240 Stainless Steel Plate, Sheet and Strip Procurement GuideASTM A240/A240M is the principal ASTM product specification for chromium, chromium-nickel and chromium-manganese-nickel stainless steel plate, sheet and strip used in pressure-vessel and general applications. A valid order still needs the exact grade, product form, dimensions, finish, condition and referenced A480 requirements.
  • ASTM A276 vs A479 Stainless Steel Bars and ShapesASTM A276/A276M covers stainless steel bars and selected shapes for general corrosion-resistant and high-temperature uses, while ASTM A479/A479M covers stainless bars and shapes for boiler and other pressure-vessel construction. A shared alloy grade does not make the two specifications automatically interchangeable.
  • ASTM A312 Austenitic Stainless Steel Pipe Specification GuideASTM A312/A312M covers seamless, straight-seam welded and heavily cold worked welded austenitic stainless steel pipe for high-temperature and general corrosive service. The specification is only one layer of the order: grade, manufacturing route, pipe dimensions, heat treatment, examination and service requirements remain essential.
  • ASTM A269 vs A213 Stainless Steel Tubing Selection GuideASTM A269/A269M covers seamless and welded stainless tubing for general corrosion-resistant and low- or high-temperature service, whereas ASTM A213/A213M covers seamless ferritic and austenitic alloy-steel boiler, superheater and heat-exchanger tubes. Service wording, manufacturing route and acceptance make them different products.
  • ASTM A36 vs A572 Structural Steel Procurement GuideASTM A36/A36M covers carbon structural steel, while ASTM A572/A572M covers high-strength low-alloy columbium-vanadium structural steel in named grades and product limits. They are product specifications, not universal strength labels, and must be ordered with the applicable A6 general requirements, member geometry, toughness and fabrication controls.
  • EN 10025 Structural Steel Product Standard SystemEN 10025 is a multi-part European product-standard series for hot-rolled structural steels. Procurement requires the correct series part, complete steel name, delivery condition, product dimensions and EN 10025-1 general requirements; writing only S235, S355 or a material number leaves essential toughness and delivery information unresolved.
  • ASTM A516 Pressure Vessel Plate Procurement GuideASTM A516/A516M covers carbon-steel plate intended primarily for welded pressure vessels in moderate- and lower-temperature service. It contains four strength grades, but a safe order also needs plate thickness, heat-treatment condition, impact requirements, ASTM A20 general requirements, construction-code acceptance and traceable inspection documentation.
  • EN 10028 Pressure-Purpose Steel Product Standard SystemEN 10028 is a seven-part European series for flat steel products used for pressure purposes. Part 1 gives general requirements and the remaining parts separate non-alloy, alloy, fine-grain, nickel-alloy, quenched-and-tempered and stainless families. Procurement must identify the correct part, complete steel name, dimensions, delivery condition and pressure-equipment acceptance basis.
  • ASTM A53 vs A106 Carbon Steel Pipe Procurement GuideASTM A53/A53M covers black and hot-dip zinc-coated welded and seamless steel pipe, while ASTM A106/A106M covers seamless carbon-steel pipe for high-temperature service. Similar grade letters or dimensions do not make them equivalent; service, manufacturing route, NPS and schedule, ends, testing and piping-code acceptance must be defined.
  • ASTM A653 Galvanized and Galvannealed Sheet Procurement GuideASTM A653/A653M covers continuously hot-dip zinc-coated and zinc-iron-alloy-coated steel sheet. A correct order separates the base-steel designation from coating designation, sheet dimensions, surface treatment and intended forming. G90 is a coating class—not a substrate grade or a promise of service life—and A924 general requirements also apply.
  • EN 10346 Continuously Hot-Dip Coated Steel Procurement GuideEN 10346 specifies continuously hot-dip coated steel flat products for cold forming, including multiple substrate and metallic-coating families. The current published 2015 edition remains the purchasing basis unless a contract adopts another edition; a 2025 draft revision is evidence of revision activity, not a replacement standard for production orders.
  • JIS G 3302 Galvanized Steel Sheet and Strip Procurement GuideJIS G 3302:2022 covers hot-dip zinc-coated steel sheet and strip, including flat and corrugated products within its scope. Commercial callouts such as SGCC must remain tied to the active JIS edition, coating-mass designation, dimensions, surface treatment, shape and application; the grade symbol alone is not a complete coated-sheet order.
  • ASTM A681 Alloy Tool Steel Product and Procurement GuideASTM A681-24 covers available wrought alloy tool-steel products used to make tools, dies and fixtures. It spans several product forms and tool-steel families, but an order still needs the exact grade, form, condition, dimensions, quality controls and responsibility for final heat treatment.
  • ISO 4957 Tool Steel Families and Procurement GuideISO 4957:2018 specifies internationally important wrought tool-steel grades across non-alloy cold-work, alloy cold-work, alloy hot-work and high-speed families. It also addresses several product routes and delivery conditions, but does not promise global availability or exact equivalence to ASTM, EN, JIS or proprietary grades.
  • ASTM A29/A29M Carbon and Alloy Steel Bar General RequirementsASTM A29/A29M-23 supplies common requirements for hot-wrought carbon and alloy steel bars ordered under individual ASTM product specifications. It is not a standalone grade or universal bar specification: the purchase order must first name the applicable product document, grade, section, condition and mechanical or hardenability requirements.
  • EN 10083 to ISO 683 Quenched and Tempered Steel GuideEN 10083 remains common on legacy drawings for quenching-and-tempering steels, but the former EN architecture has been superseded in current purchasing by adopted ISO 683 parts. Buyers should not silently rewrite a drawing: identify the legacy requirement, confirm the accepted replacement and preserve grade, form, delivery condition, size and inspection obligations.
  • ASTM B152 Copper Sheet, Strip, Plate and Rolled Bar GuideASTM B152/B152M-24 covers copper sheet, strip, plate and rolled bar in listed copper UNS grades. A complete purchase separates copper type, temper, product form, unit system, dimensions, edges, surface and electrical or mechanical acceptance; ASTM B248/B248M supplies referenced general flat-product requirements.
  • ASTM B187 Copper Bus Bar, Rod, Bar and Shapes GuideASTM B187/B187M-26 covers copper conductor bar, rod and shapes for electrical bus applications plus rod, bar and shapes for general purposes. The order must distinguish electrical from general duty and define UNS, temper, section, length, straightness, edge radius, conductivity, mechanical tests and B249 general requirements.
  • ASTM B265 Titanium Sheet, Plate and Strip Procurement GuideASTM B265-25 covers annealed titanium and titanium-alloy strip, sheet and plate across commercially important grades. Grade identity alone is incomplete: buyers must state product form, thickness, dimensions, annealed condition, surface, flatness, bend requirements, interstitial chemistry, testing and application qualification.
  • ASTM B348 Titanium Bar and Billet Procurement GuideASTM B348/B348M-25 covers annealed titanium and titanium-alloy bars and billets. Procurement must distinguish bar from billet and specify grade, section, length, annealed condition, surface preparation, dimensional tolerance, tensile testing, interstitial chemistry and intended machining or forging route.
  • ASTM B338 Titanium Condenser and Heat-Exchanger Tube GuideASTM B338-17(2026) covers seamless and welded titanium and titanium-alloy tubes for surface condensers, evaporators and heat exchangers. A complete order identifies grade, manufacturing route, outside diameter, wall, length, heat treatment, weld condition, testing, cleanliness and equipment-design requirements.
  • ASTM B443 Nickel Alloy 625 Flat Product Procurement GuideASTM B443-26 covers rolled UNS N06625 and UNS N06219 nickel-alloy plate, sheet and strip. N06625 includes distinct heat-treatment grades for different service-temperature intent. Buyers must specify alloy, grade/condition, product form, dimensions, surface, tests, B906 general requirements and equipment-code acceptance.
  • ASTM B446 Nickel Alloy 625 Rod and Bar Procurement GuideASTM B446-26 covers hot- and cold-worked rod and bar in UNS N06625, N06219 and N06650. N06625 includes annealed, solution-annealed and solution-annealed/cold-worked strength conditions. A complete order states alloy, grade, working route, section, length, straightness, surface, tests and end-use qualification.
  • ASTM B622 Seamless Nickel Alloy Pipe and Tube GuideASTM B622-23 covers seamless pipe and tube in listed nickel and nickel-cobalt alloys, normally supplied solution annealed and descaled. Procurement must distinguish pipe from tube, select the exact UNS alloy, dimensions and condition, and define tension, hydrostatic or nondestructive electric testing plus B829 general requirements.
  • ASTM A500 Structural Tubing Grades and Procurement GuideASTM A500/A500M-23 covers cold-formed welded and seamless carbon-steel structural tubing in round, square, rectangular and special shapes. A complete HSS order identifies grade, route, section dimensions, wall, length, finish, tests and any project-specific notch-toughness or fabrication requirements.
  • ASTM A513 Mechanical Tubing Types and Procurement GuideASTM A513/A513M-25 covers electric-resistance-welded carbon and alloy steel mechanical tubing made from hot- or cold-rolled steel in round and shaped sections. Purchasing depends on grade, Type 1–6 processing route, thermal condition, geometry, dimensional precision, surface and end-use fabrication tests.
  • ASTM A333 Low-Temperature Pipe Grades and Procurement GuideASTM A333/A333M-24 covers nominal-wall seamless and welded carbon and alloy steel pipe for low-temperature service and other applications requiring notch toughness. The order must connect grade, route, heat treatment, size and wall to impact-test temperature, specimen basis, pressure/NDE and the governing piping code.
  • ASTM A335 Alloy Steel Pipe Grades and Procurement GuideASTM A335/A335M-26 covers nominal- and minimum-wall seamless ferritic alloy-steel pipe intended for high-temperature service. Procurement requires the exact P grade, size and wall basis, heat treatment, forming/welding intent, mechanical and hardness evidence, hydrostatic or NDE acceptance and code-qualified design data.
  • ASTM B209 Aluminum Sheet and Plate Procurement GuideASTM B209/B209M-21a covers aluminum and aluminum-alloy flat sheet, coiled sheet and plate in listed alloys, tempers and finishes. A defensible order states product form, unit document, alloy-temper, dimensions, finish, flatness, grain direction, test evidence and any marine, aerospace or fabrication qualification beyond B209.
  • ASTM B221 Aluminum Extrusion Alloys, Tempers and Procurement GuideASTM B221/B221M-21 covers aluminum and aluminum-alloy extruded bars, rods, wire, profiles and general-purpose tubes in listed alloys and tempers. Procurement must combine alloy-temper with the exact extrusion drawing, form, unit document, tolerances, straightness, surface, heat treatment and pressure or structural exclusions.
  • ASTM B241 Aluminum Seamless Pipe and Extruded Tube GuideASTM B241/B241M-22 covers aluminum and aluminum-alloy seamless pipe and seamless round extruded tube intended for pressure applications. The buying identity includes pipe versus tube, alloy-temper, hollow-ingot die-and-mandrel route, NPS or exact OD/wall, length, heat treatment, leak testing, ends and code requirements.
  • ASTM B210 Drawn Seamless Aluminum Tube Procurement GuideASTM B210/B210M-26 covers drawn seamless aluminum and aluminum-alloy tubes in straight lengths and coils for general-purpose and pressure applications. Buyers must specify alloy-temper, straight or coil form, OD, wall, length, drawing condition, surface, flattening/flaring, leak-test route and application-specific exclusions.
  • ASTM A123 Fabricated Steel Hot-Dip Galvanizing GuideASTM A123/A123M-24 covers zinc hot-dip coatings applied to covered iron and steel products, including many assemblies galvanized after fabrication. It requires article-category coating acceptance, but successful procurement also needs galvanizing-aware design, steel/fabrication disclosure, venting, drainage, distortion control, inspection and repair agreement.
  • ISO 1461 Hot-Dip Galvanized Coating Procurement GuideISO 1461:2022 specifies general properties and test methods for hot-dip galvanized coatings applied by zinc-melt immersion to fabricated iron and steel articles, including certain castings. Orders must still define article category, base material, design for galvanizing, inspection/sampling, local repair, documentation and exclusions for continuous products or automatic-line pipe.
  • ASTM A792 55% Aluminum-Zinc Coated Steel Sheet GuideASTM A792/A792M-25a covers steel sheet in coils and cut lengths hot-dip coated with 55% aluminum-zinc alloy for corrosion resistance, heat resistance or both. A complete order separates base-steel designation/grade from coating designation, unit system, dimensions, surface treatment, forming, paintability, testing and storage requirements.
  • ASTM A755 Prepainted Metallic-Coated Steel Sheet GuideASTM A755/A755M-18(2024) covers metallic hot-dip-coated steel sheet coil-coated with organic films for exterior exposed building products.
