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
5、ated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
