Induction Hardening

Induction hardening involves transferring energy to the workpiece using a copper coil. This method allows for large amounts of energy to be transferred in a short time, as the heat is generated within the workpiece. We use induction hardening as a process for surface hardening. In this process, we impart a high-hardness surface layer to workpieces with either low or high strength. This surface layer, which is usually locally confined, is heated inductively with an inductor coil, bringing it to the necessary hardening temperature. By quenching with a spray directed at the component and using a special quenching medium, martensite formation in the surface layer is achieved. All steels with a sufficient carbon content (starting from about 0.3% C) are suitable for induction hardening. However, steels with lower carbon content can also be induction hardened.
