1.1This specification covers requirements for forged steel shapes for highly stressed structural members requiring yield strengths in excess of 140 ksi [965 MPa].
1.2This specification is not intended for applications limited by creep deformation.
1.3Twenty-eight grades are covered by this specification. Selection will depend upon design, service conditions, and mechanical properties required.
1.4Supplementary 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.
1.5The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.6Unless the order specifies the applicable “M” specification designation, the material shall be furnished to the inch-pound units.
