(Specification)Standard Specification for Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel Bars and Shapes
Standard Specification for Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel Bars and Shapes
ABSTRACT
This 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. Type 631 and 632 stainless steels contain a large amount of ferrite in the microstructure and can have low ductility in forgings and large diameter bars. Material of types other than XM-16, XM-25, and Type 630 shall be furnished in the solution-annealed condition, or in the equalized and oven-tempered condition. Types 630, XM-16, and XM-25 may be furnished in the solution-annealed or age-hardened condition. Type UNS S46910 shall be furnished in solution annealed, cold-worked or aged-hardened condition. Shapes may be subjected to either Class A or Class C preparation for removal of visible surface imperfections. The material shall be subjected to tension, impact, and hardness tests.
SCOPE
1.1 This 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.
1.2 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; 840°F [450°C] for Type UNS S46910. 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. Type UNS S46910 is suitable for machining in the solution-annealed, cold-worked, and aged-hardened condition.
1.3 Types 631 and 632 contain a large amount of ferrite in the microstructure and can have low ductility in forgings and larger diameter bars. Applications should be limited to small diameter bar.
1.4 The values stated in either inch-pound units or SI (metric) units are to be regarded separately as standards; within the text and tables, the SI units are shown in [brackets]. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other. Combining values from the two systems may result in nonconformance with the specification.
1.5 Unless the order specifies an “M'' designation, the material shall be furnished to inch-pound units.
Note 1—For forgings, see Specification A 705/A 705M.
Note 2—For billets and bars for forging see Specification A 314.

Designation:A 564/A 564M–02a Designation: A 564/A 564M – 04 (Reapproved 2009)
Standard Specification for
Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel
Bars and Shapes
This standard is issued under the fixed designationA 564/A 564M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope *
1.1 This 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.
1.2 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; 840°F [450°C] for Type UNS S46910. 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.Type
UNS S46910 is suitable for machining in the solution-annealed, cold-worked, and aged-hardened condition.
1.3 Types 631 and 632 contain a large amount of ferrite in the microstructure and can have low ductility in forgings and larger
diameter bars. Applications should be limited to small diameter bar.
1.4 The values stated in either inch-pound units or SI (metric) units are to be regarded separately as standards; within the text
and tables, the SI units are shown in [brackets]. The values stated in each system are not exact equivalents; therefore, each system
must be used independent of the other. Combining values from the two systems may result in nonconformance with the
specification.
1.5 Unless the order specifies an “M’’ designation, the material shall be furnished to inch-pound units.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation:A 564/A 564M–04 Designation: A564/A564M – 04 (Reapproved 2009)
Standard Specification for
Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel
Bars and Shapes
This standard is issued under the fixed designationA564/A564M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope *
1.1 This 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.
1.2These1.2 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; 840°F [450°C] for Type UNS S46910. 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.Type
UNS S46910 is suitable for machining in the solution-annealed, cold-worked, and aged-hardened condition.
1.3 Types 631 and 632 contain a large amount of ferrite in the microstructure and can have low ductility in forgings and larger
diameter bars. Applications should be limited to small diameter bar.
1.4 The values stated in either inch-pound units or SI (metric) units are to be regarded separately as standards; within the text
and tables, the SI units are shown in [brackets]. The values stated in each system are not exact equivalents; therefore, each system
must be used independent of the other. Combining values from the two systems may result in nonconformance with the
specification.
1.5 Unless the order specifies an “M’’ designation, the material shall be furnished to inch-pound units.
NOTE1—For forgings, see Specification A 705A 705/A 705M/A 705M. 1—For forgings, see Specification A705/A705M.
NOTE 2—For billets and bars for forging see Specification A 314A314.

6.1 Each alloy covered by this specification shall conform to the chemical requirements specified in Table 1.
6.2 Methods and practices relating to chemical analysis required by this specification shall be in accordance withTest Methods,
Practices, and Terminology A 751A751.
7. Mechanical Properties Requirements
7.1 The material, as represented by mechanical test specimens, shall conform to the mechanical property requirements specified
in Table 2 or Table 3 and shall be capable of developing the properties in Table 4 when heat treated as specified in 5.1.
7.2 Samples cut from bars for forging stock shall conform to the mechanical properties ofTable 2 andTable 4 when heat treated
as specified in Table 2 and Table 4.
