Induction hardening and tempering

High-frequency induction hardening refers to a heat treatment method that uses high-frequency current (30K-1000KHZ) ワークの表面を局所的に加熱・冷却して表面硬化層を形成します。.

この方法では、ワークの表面を一定の深さまで強化するだけです。, 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.
