Induction Hardening

Induction Hardening is a form of heat treatment in which parts are heated by induction heating and then quenched. The quenched metal undergoes a transformation which creates a high surface hardness with a deep case capable of handling extremely high loads. Fatigue strength is increased by the development of a soft core surrounded by an extremely tough outer layer. Induction Hardening is used to selectively harden areas of a part or assembly without aff ecting the properties of the part as a whole.
