Induction hardening is a heat treatment process that locally or entirely hardens the surface of metal workpieces through the principle of electromagnetic induction. This process features fast heating speed, minimal deformation, low energy consumption, and strong controllability, and is widely used for surface strengthening of components such as gears, shafts, and guide rails.
