Standard Specification for Superstrength Alloy Steel Forgings
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This specification covers requirements for forged steel shapes for highly stressed structural members requiring yield strengths in excess of 140 ksi [965 MPa].
1.2 This specification is not intended for applications limited by creep deformation.
1.3 Twenty-seven grades are covered by this specification. Selection will depend upon design, service conditions, and mechanical properties required.
1.4 Supplementary requirements are provided for use when additional testing or inspection is desired. These shall apply only when specified individually by the purchaser in the order.
1.5 The values stated in either inch-pound or SI (metric) units are to be regarded separately as standards. Within the text and tables, the SI units are shown in brackets. The values in each system are not exact equivalents; therefore, each system must be used independently of each other. Combining values from the two systems may result in non-conformance with the specification.
