410 Stainless Steel Bar

Procurement guide for heat-treatable 410 martensitic stainless bar, covering annealed or hardened condition, hardness, machining allowance, testing and heat-treatment traceability.

03Grade-product

Specifications and dimensions

State round, square, hexagonal or flat bar; diameter or width × thickness; length and applicable size tolerance.
State hot-finished, cold-finished, peeled, turned, ground or centerless-ground presentation and straightness class.
Define surface roughness, decarburization/scale condition, chamfered ends, ultrasonic-test class and bundle mass where required.

Standards and supply condition

ASTM A276/A276M for stainless steel bars and shapes
ASTM A484/A484M plus the exact ordered heat-treatment condition

Manufacturing and processing

Billet is hot rolled or forged, solution annealed or heat treated as required, straightened and descaled before final finishing.
Cold drawing, peeling, turning and grinding change tolerance, surface, residual stress and mechanical response; order the exact route.

Typical applications

Valve, pump, shaft and fastener components
Wear-resistant machine parts after heat-treatment qualification
General cutlery and tooling components where the specification permits

Quality and acceptance controls

Verify heat identity, grade chemistry, heat-treatment condition and mechanical results against the material certificate.
Measure size, ovality, straightness, length and surface condition using the ordered tolerance table.
Inspect laps, seams, cracks, grinding damage and end defects; perform ultrasonic or surface NDE when specified.
Confirm marking, heat-to-bundle traceability, rust-free packing and separation from carbon-steel contamination.

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

410 designation does not define bar/strip/angle dimensions, condition, finish, tolerance or acceptance; the product standard and order do.
410 properties and corrosion behavior depend strongly on heat treatment; annealed and hardened bars are not interchangeable.
