ASTM A564 Specification for Hot-rolled and Cold-finished Age-hardening Stainless Steel Bars and Shapes

ASTM A564 Specification for Hot-rolled and Cold-finished Age-hardening Stainless Steel Bars and Shapes

ASTM A564 Specification covers bars and shapes of age hardening stainless steels. Hot-finished or cold-finished  rounds, squares, hexagons, bar shapes, angles, tees, and  channels are included; these shapes may be produced by  hot rolling, extruding, or forging. Billets or bars for reforging may be purchased to this specification.  

These steels are generally used for parts requiring  corrosion resistance and high strength at room temperature,  or at temperatures up to 600°F [315°C]; 700°F [370°C] for  Type 632. They are suitable for machining in the solution annealed condition after which they may be age-hardened  to the mechanical properties specified in Section 7 without  danger of cracking or distortion. Type XM-25 is machinable in the as-received fully heat treated condition.
