Standard Specification for Alloy Steel Forgings for High-Strength Pressure Component Application
|Publication Date:||10 September 1999|
|ICS Code (Steels for pressure purposes):||77.140.30|
1.1 This specification covers requirements for high-strength quenched and tempered alloy steel forgings for pressure vessels, isostatic presses, shock tubes, and similar components.
1.2 These materials are not intended for welded construction.
1.3 Three grades of nickel-chromium-moly
1.4 The values stated in either inch-pound units or SI (metric) units are to be regarded separately as the standard. Within the text and tables, the SI units are shown in brackets. 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 specification.
1.5 Unless the order specifies the applicable "M" specification designation, the material shall be furnished to the inch-pound units.
