本标准为ASTM A959-2009，标准的中文名称为规定锻制不锈钢统一标准等级成份的指南，标准的英文名称为Standard Guide for Specifying Harmonized Standard Grade Compositions for Wrought Stainless Steels，在2009-03-15开始实施。
本标准作废日期为2011-06-01。被标准ASTM A959-2011替代。
1.1 This guide provides a guide to ASTM Subcommittees A01.06, A01.10, A01.17, A01.22, and A01.28 for specifying chemical composition limits of wrought stainless steels. It is intended that these recommended grade composition limits be suitable for adoption by other standardization bodies that prepare standards for stainless steel products. 1.2 Included in this guide are the recommendations for determining the number of significant figures for specifying chemical composition from Test Methods, Practices, and Terminology A 751. 1.3 All stainless steel UNS numbers and the stainless steel grades in all standards overseen by the aforementioned ASTM subcommittees have been included, except those grades applicable to restricted special end uses and alloys containing less than 10.5 % minimum chromium. 1.4 Not addressed are minor composition modifications which a specific product subcommittee may find necessary to accommodate effects of normal processing or to enhance fabricability by
