Induction Hardening

During the induction hardening process the surface of the work piece will be heated up to the austenitization temperature. This is realized with changing magnetic fields which induce electrical power into the surface. After the respective temperature and the predetermined depth are reached the work piece will be quenched with a matching quenching agent. This process hardens only the surface and leaves the core unaffected. This way the surface becomes wear-resistant and the core keeps the characteristics generated with eventual previous heat treatments. Several millimetres of hardening depths can be reached with the induction hardening process.
