1.1 This specification covers laser and laser hybrid welded austenitic, ferritic, and duplex (ferritic-austenitic) stainless steel bars, plates, and shapes of structural quality for use in bolted or welded structural applications.

1.2 Shapes covered in this specification include those classified in Article 3.1.2 of Specification A6/A6M, Specification A554 square and rectangular hollow sections, and additional shapes, including customized, that are made from two or more shapes or plates.

1.3 This specification establishes the minimum requirements for manufacturing of laser and laser hybrid welded stainless steel shapes.

1.4 This specification refers to Specifications A240/A240M, A276/A276M, A554, or A479/A479M for chemical requirements, but the mechanical test requirements are determined by the mechanical properties section of this standard.

1.5 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.

1.6 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.

1.7 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.
