SPECIFICATION FOR CHROMIUM AND CHROMIUMNICKEL STAINLESS STEEL PLATE, SHEET, AND STRIP FOR PRESSURE VESSELS AND FOR GENERAL APPLICATIONS
SA-240/SA-240M
1.
Scope 1.1 This specication covers chromium, chromiumnickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications. 1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specication. 1.3 This specication is expressed in both inch-pound and SI units. However, unless the order species the applicable M specication designation (SI units), the material shall be furnished in inch-pound units.
