Scope* 1.1 This specification2 covers chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications. 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 This specification is expressed in both inch-pound and SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished in inch-pound units. 1.4 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. 3. General Requirements 3.1 The following requirements for orders for material furnished under this specification shall conform to the applicable requirements of the current edition of Specification A 480/A 480M. 3.1.1 Definitions; 3.1.2 General requirements for delivery; 3.1.3 Ordering information; 3.1.4 Process; 3.1.5 Special tests; 3.1.6 Heat treatment; 3.1.7 Dimensions and permissible variations; 3.1.8 Workmanship, finish and appearance; 3.1.9 Number of tests/test methods; 3.1.10 Specimen preparation; 3.1.11 Retreatment; 3.1.12 Inspection; 3.1.13 Rejection and rehearing; 3.1.14 Material test report; 3.1.15 Certification; and 3.1.16 Packaging, marking, and loading. 2.
