1.1This specification2covers chromium,chromium-nickel, and chromium-mangane-nickel stainless steel plate,sheet, and strip for pressure vesls and for general applications. 1.2The values stated in either inch-pound units or SI units are to be regarded parately as standard.The values stated in each system are not exact equivalents;therefore,each system must be ud independently of the other.Combining values from the two systems may result in nonconformance with the specification.
1.3This specification is expresd 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.快乐的音乐
