This specification covers a premium aircraft-quality steel in the form of bars, forgings, mechanical tubing, flash welded rings, and stock for forging or flash welded rings.

Application

These products have been used typically for parts requiring through-hardening, without liquid quenching, to yield strength of 200 ksi (1379 MPa) and where such parts may require welding during fabrication, but usage is not limited to such applications.
