High-frequency hardening refers to a heat treatment method that uses high-frequency current (30K-1000KHZ) to locally heat and cool the surface of the workpiece to obtain a surface hardened layer.

This method only strengthens the surface of the workpiece to a certain depth, while the core basically maintains the structure and performance before treatment, so a combination of high strength, high wear resistance and high toughness can be obtained. And because it is localized heating, it can significantly reduce quenching deformation and reduce energy consumption.

It is precisely because high-frequency quenching has the above characteristics that it is widely used in the mechanical processing industry.
