STEEL BARS AND FORGINGS, NITRIDING 1.6Cr – 0.35Mo – 1.13Al (0.38 – 0.43C) Heat Treated, 112,000 psi (772 MN/M2) Tensile
|Publication Date:||15 May 1971|
Form: This specification covers a nitriding grade of aircraft-quality, low-alloy steel in the form of heat treated bars and forgings, and of forging stock.
Application: Primarily for nitrided parts requiring highest surface hardness, resistance to heat, and less distortion that parts made from steel requiring quenching to case harden. The steel may be case hardened in dissociated ammonia gas to give a minimum case hardness of 900 HV.
