2、f last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers laser-fused stainless steel bars,plates, and shapes of structural quality for use in bolte

3、d orwelded structural applications.1.2 Shapes covered in this specification include those clas-sified in Article 3.1.2 of Specification A6/A6M and those thatare made from two or more shapes or plates.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standar

4、d. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associ
