air-hardening steel

air-hardening steel
sometimes referred to as self-hardening steel. A steel that becomes fully hardened when cooled in air from above its critical point and does not require rapid quenching by oil or water. The risk of distortion is greatly reduced by air hardening. High speed steel was one of the earliest examples of this type of steel.
