Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other. Type and stainless steels contain a large amount of ferrite in the microstructure and can have low ductility in forgings and large diameter bars.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Awtm on Standards, at the address shown below.
Billets or bars for reforging may be purchased to this specication. 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.
ASTM A 564
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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.
Shapes may be subjected to either Class A or Class C preparation for removal of visible surface imperfections. A superscript epsilon indicates an editorial change since the last revision or reapproval. Astmm Documents purchase separately A546 documents listed below are referenced within the subject standard but are not provided as part of the standard.
Type UNS S shall be furnished in solution annealed, cold-worked or aged-hardened condition. Historical Version s – view previous versions of standard.
Combining values from the two systems may result in nonconformance with the specification. On sizes 12 in. When specied, the material, as represented by impact test specimens, shall be capable of developing the impact property requirements specied in Table 4 when heat treated in accordance with 5.
D BH for rounds cold drawn after solution treating. Originally approved in Number of Tests 8. This specification covers bars and shapes of age-hardening stainless steels. The limiting permanent offset shall be 0.

Type UNS S is suitable for machining in the solution-annealed, cold-worked, and aged-hardened condition. Applications should be limited to small diameter bar.
They are suitable for machining in the solution-annealed condition after which they may be age-hardened to the mechanical properties specied in Section 7 without danger of cracking or distortion.
Up to 6 in. Up to 4 in. C Unless otherwise noted, temperatures shown are suggested temperatures and may be varied to obtain required tensile properties. Warm in air to room temperature. Combining values from the two systems may result in nonconformance a54 the specification. Limits are in percent maximum unless shown as a range or stated otherwise.
The values stated in each system are not exact equivalents; therefore, each asgm must be used independent of the other.
