Standard Specification for Alloy Steel Forgings for High-Strength Pressure Component Application
|Publication Date:||1 July 2018|
|ICS Code (Steels for pressure purposes):||77.140.30|
This specification2 covers requirements for highstrength quenched and tempered alloy steel forgings for pressure vessels, isostatic presses, shock tubes, and similar components.
These materials are not intended for welded construction.
Three grades of nickel-chromium-moly
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.
Unless the order specifies the applicable "M" specification designation, the material shall be furnished to the inchpound units.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
