3、f the Department of Defense.1. Scope*1.1 This specification2 covers chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, andstrip for pressure vessels and for general applications.1.2 The values stated in either SI units or inch-pound units are to be regarded separa
4、tely as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.3 This specification is expressed in both inch-pound and SI units. H
5、owever, 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 responsibilityof the user of this standa
6、rd to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.
