High Frequency Induction Quenching is a form of heat treatment in which a metal part, High Frequency Induction Quenching is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly
