ASTM A965/A965M-02

Standard Specification for Steel Forgings, Austenitic, for Pressure and High Temperature Parts

SCOPE
1.1 This specification covers austenitic stainless steel forgings for boilers, pressure vessels, high temperature parts, and associated equipment.
1.2 Supplementary requirements are provided for use when additional testing, inspection, or processing is required. In addition, supplementary requirements from Specification A 788 may be specified when appropriate.
1.3 This specification includes the austenitic steel forgings that were a part of A 336/A 336M.
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. 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 the applicable "M" specification designation, the material shall be furnished to the inch-pound units.
