Hardening with Induction

What is Hardening with Induction?

Induction hardening is a form of heat treatment in which a metal part with sufficient carbon content is heated in the induction field and then rapidly cooled. This increases both the hardness and brittleness of the part. Induction heating allows you to have localized heating to a pre-determined temperature and enables you to precisely control the hardening process. Process repeatability is thus guaranteed. Usually, induction hardening is applied to metal parts which need to have great surface wear resistance, while at the same time retaining their mechanical properties. After the induction hardening process is achieved, the metal workpiece needs to be quenched in water, oil or air inorder to obtain specific properties of the surface layer.
