ASTM A965/A965M-05
(Specification)Standard Specification for Steel Forgings, Austenitic, for Pressure and High Temperature Parts
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 SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.5 Unless the order specifies the applicable "M" specification designation, the material shall be furnished to the inch-pound units.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
