Standard Specification for Age-Hardening Stainless Steel Forgings
ABSTRACT
This specification covers age-hardening stainless steel forgings for general use. Materials for forgings shall consist of billets or bars and shall either be forged, rolled, or cast or a section cut from an ingot. The steel specimens shall be solution annealed and age hardened and shall conform to the required values of tensile strength, yield strength, elongation, reduction of area, hardness and impact Charpy-V. The steel materials shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, aluminum, molybdenum, titanium, copper, nitrogen, columbium, and tantalum.
SCOPE
1.1 This specification2 covers age-hardening stainless steel forgings for general use.
1.2 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.
1.3 Unless the order specifies an “M” designation, the material shall be furnished to inch-pound units.
Note 1: Bar products are covered by Specification A564/A564M.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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.
