Heat-Treating & Hardening 4140 Steel - Material ...

Jun 30, 2006 · 4140 is not case hardened by carburizing but it is frequently induction hardened to the hardness and depth you desire and beyond. If you want the core to be softer you can first normalize, or quench & temper in a furnace to the desired lower hardness level. This treatment also prepares the near surface for optimum induction hardening response.

The effects of induction hardening on wear properties of ...

The wear tests using a pin-on-disc machine showed that the induction hardening treatments improved the wear behaviour of AISI 4140 steel specimens compared to normalised AISI 4140 steel as a result of residual stresses and hardened surfaces. The wear coefficients in normalised specimens are greater than that in the induction hardened samples.

How to Harden 4140 Steel eHow

How to Harden 4140 Steel. Hardening steels involves the basic process of heating the steel to organize the crystalline structure in a uniform way and then rapidly cooling it by quenching it to lock the molecular make-up of the steel. However, different steels have different hardening steps to follow. Some of the most difficult steels to harden are...
