This nickel molybdenum alloy is a carburizing steel capable of developing high case hardness and core toughness. It responds well to carburizing and hardening to produce a case of uniform hardness with relative freedom from distortion.

It is produced by the best steelmaking practice for aircraft quality steels, and is then vacuum degassed to meet the magnetic particle inspection standards of AMS 2301.
