Metal hardening is used to improve the wear resistance, hardness and service life of surfaces. At Incoil, we specialise in induction hardening, where the surface of a metal component is rapidly heated using an electromagnetic field and then cooled to transform it into a hard martensitic structure.
This produces a component with a hard, wear-resistant surface layer while the core retains its toughness and fracture resistance. Contact us to find the right solution for your components.
Unlike traditional heat treatment methods, induction hardening is a contactless and highly precise process. Heating takes place locally with a high degree of repeatability, minimising the risk of deformation and providing greater control over the final result. The method is suitable for both single-component production and automated production series.
An electromagnetic field is generated in an induction coil, heating the surface of the metal to the austenitising range, typically 800–900 °C.
To reduce internal stresses and adjust hardness, the component can be tempered after hardening.
Induction hardening is carried out in several stages to ensure an optimal result:

Gas brazing is an established method for joining metals where heat from a gas flame is used to melt a filler metal. The method is used in, among other areas,
Metal hardening is a heat treatment process used to alter the properties of the material in order to increase hardness, wear resistance, and resistance to mechanical impact.
Hardening of steel is a metallurgical process in which the internal structure of the material is altered to increase hardness and wear resistance. The process is used when components must withstand high
