Steel Bars and Forgings, Nitriding 1.6Cr - 0.35Mo - 1.1Al (0.38 - 0.43C) Hardened and Tempered, 112 ksi (772 MPa) Tensile Strength
|Publication Date:||1 July 1991|
Form: This specification covers an aircraft-quality low-alloy steel in the form of heat treated bars and forgings, and of forging stock.
Application: Primarily for nitrided parts requiring high surface hardness, resistance to heat, and less distortion than parts made from steel requiring quenching to case harden. This steel may be case hardened in dissociated ammonia gas to give a minimum case hardness of 900 HV.
