Description / Abstract:
Form
This specification covers a premium aircraft-quality steel in the form of bars, forgings, mechanical tubing, flash welded rings up through 10.000 inches (254.00 mm) inclusive in diameter or least distance between parallel sides, and stock for forging or flash welded rings.
Application
These products have been used typically for parts requiring through-hardening, without liquid quenching, to a yield strength of 270 ksi (1862 MPa) and higher and where such parts may require welding during fabrication, but usage is not limited to such applications.
