Induction hardening is a special process of heating the workpiece only on the desired surface, which allows its core to remain tough.

This process is very suitable for gears, shafts, guides and the like.

This method of heating workpieces is also used in soldering - especially pipes.

Product examples

Induction hardening is a process in which the desired metal is heated in a specific location and then cooled. This phase is called austenitization, and the second is called austenite transformation. With this process we obtain the desired microstructure and the optimal combination of mechanical properties. Induction hardening comes into play when we want to harden a specific part of the workpiece.

Heating of the material is carried out with high-frequency or low-frequency current. In the latter, an electric current flows through a loop and creates an alternating magnetic field. This ensures that an electric current is induced on the surface. The frequency is what determines the depth to which we want to heat the product.

Induction hardening, which is one of the main services in our offer, has many advantages over other heat treatments. It is suitable for serial orders, as it allows for easier automation of the process, easier regulation of the hardening depth, higher speeds and less product deformation. For larger workpieces, it is convenient because it allows hardening only on the loaded parts of the workpiece (e.g. only the tread of a wheel, etc.)
