AMS6514B Steel, Maraging, Bars, Forgings, Tubing, and Rings 18.5Ni - 9.0Co - 4.9Mo - 0.65Ti - 0.10Al Consumable Electrode Vacuum Melted, Annealed

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.

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.
