Scope
This standard specifies the ordering content, materials, and manufacturing methods, chemical composition requirements, mechanical properties, non-destructive testing requirements, repair, and product identification for forged parts of ultra-high strength alloy steel with a yield strength greater than 965 MPa (hereinafter referred to as "forged parts"). This standard applies to forged parts of ultra-high strength alloy steel. This standard is not suitable for use in situations where creep deformation is a limiting factor. Note: This standard covers 27 grades, and the selection of grades is based on the required design, usage conditions, and mechanical properties.
