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.

Induction tempering process aims at optimizing the toughness and ductility of hardened workpieces.

The induction tempering is effective and precise. Induction tempering equipment could seamlessly connect with hardening machines that workpiece could be produced in one-stop for effective and precise treat. Comparing with tempering in furnace, the induction tempering could carefully control the temperature and delivers to workpiece uniformly. The heating process is quick and stable which safeguards the yield and quality.

Induction hardening and tempering treatment is a combination of which work piece heat by induction to hardening temperature for certain time and rapidly quenching, then heat again by induction for tempering.

Induction hardening and tempering production line is generally employed in the production of chain, threaded bar, pipe and other workpieces. We has developed matured heating solutions that integrates hardening and tempering process together to improve efficiency of manufacturing.
