Induction hardening is favored for parts that are subject to heavy loading. Typical applications include axles, saw blades, shafts, stampings, spindles, gears and most symmetrical parts. Induction hardening treatment is widely used for surface hardening steel, but can be used with other materials as well.
Induction hardening is a metal heat treatment process that offers a controllable and localized method of heat without contact to the metal parts or components being heated. The heat is generated by inducing an electric current to flow in the object to be heated. This provides a very economical, targeted and rapid heat treating of conductive materials.
