How to Harden 4140 Steel eHow

4140 is relatively easy to harden. 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. How to heat treat 4140 - The Home Machinist!Mar 20, 2011 · Re:How to heat treat 4140. Heat to 1500-1600° F and hold 1-1/2 hour per inch of greatest thickness. Quench into 150° F oil. Temper immediately after quenching, before the part has cooled to below 150° F.
