Scope

This specification covers an aircraft-quality, low-alloy steel in the form of bars and forgings. These products have been used typically for parts, such as nuts, bolts, and screws, 1.50 inch (38.1 mm) and under in section thickness, requiring a minimum tensile strength of 125 ksi (862 MPa) but usage is not limited to such applications.
