induction hardening for hardware tools

Induction hardening is a form of heat treatment in which a metal part 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 without affecting the properties of the part as a whole.
Induction Hardening is one of Induction heating's main application areas. Thousands of our hardening solutions are at work around the world, many of them within the automotive industry.
