We can improve the stiffness, tenacity, fatigue strength of the metal through the cooperation of the hardening and different temperature tempering. It can also gain the synthesized mechanical properties in order to satisfy the different operating requirement. The induction hardening machine can make some steel with special performance to gain a certain physical and chemical properties. For example, the induction hardening can increase the ferromagnetism of the permanent magnet steel and the stain resistance.
The hardening process can be divided into the single liquid hardening, double medium hardening, martensite step hardening and bainite isothermal hardening. So, we need to choose the proper hardening methods.

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. An induction heater consists of induction power supply (induction heater) and inductor (coil) that is a shaped to contour the part, and a work station where the part is held and presented to the coil.
