Form

This specification covers a corrosion-resistant, premium aircraft-quality alloy steel in the form of bars, forgings, and stock for forging.

Application

These products have been used typically for heat treated parts requiring a combination of high strength, good toughness, weldability, and stress corrosion resistance, but usage is not limited to such applications. Product after heat treatment should attain a minimum tensile strength of 280 ksi (1931 MPa).
