SAE AMS6472H-2024

Scope

This specification covers an aircraft-quality, low-alloy steel in the form of heat-treated bars and forgings, and of forging stock. This material has been used typically for nitrided parts requiring high surface hardness, resistance to heat, and less distortion than parts fabricated from steel requiring quenching to case harden, but usage is not limited to such applications. This steel may be case hardened in dissociated ammonia gas to provide a minimum case hardness of 900 HV.
