430 Stainless Steel Strip

Procurement guide for ferritic 430 stainless strip covering annealed condition, gauge, slit edge, surface finish, forming direction, magnetic behavior and coil quality.

03Grade-product

Specifications and dimensions

State thickness and slit width with product-standard tolerance, measurement method and any precision-tolerance requirement.
Define coil inside/outside diameter, maximum mass, winding direction, telescoping, camber and flatness limits.
Order slit, deburred, rounded or conditioned edges with burr height, edge wave, surface finish and protective interleaving/film.

Standards and supply condition

ASTM A240/A240M for applicable 430 stainless sheet and strip
Ordered flat-product tolerance and surface requirements

Manufacturing and processing

Hot band or cold-rolled coil is reduced and annealed to the ordered condition before precision slitting and controlled recoiling.
Tension leveling, skin passing, edge conditioning, cleaning and protective film are separate operations that require acceptance criteria.

Typical applications

Appliance trim, panels and formed components
Automotive trim and moderate-corrosion components
Decorative and general fabrication where ferritic behavior is acceptable

Quality and acceptance controls

Match grade, heat/coil number, condition and mechanical results to the certificate and slit-coil labels.
Map thickness and width across the coil; inspect camber, flatness, telescoping and winding tension.
Inspect finish, scratches, dents, roll marks, edge burr and edge wave against the approved sample.
Verify surface cleanliness and downstream forming, stamping, welding or coating compatibility where critical.

Include in your RFQ

Exact grade or alloy designation and governing product-standard edition
Product form, manufacturing route and ordered delivery condition or temper
Nominal dimensions, tolerances, length/coil geometry and quantity
Surface finish, edge/end condition, straightness/flatness and permitted defects
Fabrication, forming, machining, welding and heat-treatment requirements
Mechanical, corrosion, coating or application-specific acceptance tests
Inspection document, heat/lot traceability, marking and third-party inspection
Packing, preservation, destination, Incoterms and required delivery date

Selection limits

430 designation does not define bar/strip/angle dimensions, condition, finish, tolerance or acceptance; the product standard and order do.
430 is ferritic and normally magnetic; forming, welding and corrosion expectations must not be copied from 304.
