Induction hardening is, as in flame hardening, a thermo-physical process which is classed as a surface-layer hardening process.
Components are heated using electrical energy close to the surface, whereby the Austenising depth is primarily dictated by the frequency of the electrical current.
CNC-controlled HF (high-frequency) und MF (medium-frequency) installations are situated at the Peddinghaus Oberflächenhärtung GmbH in Gevelsberg that, through programmable control high levels of reproducibility are achievable, not just for high-volume production components.
Similar to flame hardening, the special inductors needed for the heat treatment, specific to the component requirements, are also produced in-house
Because primarily the attained hardness is dependant on the carbon content, steels suitable for induction hardening are the heat-treatable steels with a carbon content above 0.3 %, medium- and high-alloy materials, such as, e.g. X155CrVMo12.
