Induction Hardening

Induction hardening involves heating applied rapidly and locally to the steel component followed by fast cooling (quenching). High frequency electric fields quickly heat the surface of the component via inductor coils, which is then quenched using water or polymer. The microstructure is transformed by induction, for which the material must have a carbon content of at least 0,35%, and results in a localised hardened layer at the surface. 

Different shaped inductor coils are available and can be made to suit individual, specific parts.

Induction Hardening offers a cost-effective low distortion surface hardening treatment to steels, particularly where an increase in surface hardness is required whilst maintaining original core properties. 

This method is used primarily for components that are prone to wear on the surface, as well as for components with a complicated shape where only specific areas are needing to be hardened. Advantages of induction hardening are the possibility of partially hardened components in an uncomplicated way and the option of achieving extremely deep layers. The throughput times for induction hardening are comparatively short but the process does require special know-how and the use of complex tools and systems.
