heat treatment: other processes

Other processes

Deep freezing

Our deep freezer enables the temperature to be lowered to –120°C using liquid nitrogen. This achieves premature aging of steels as well as the conversion of residual austenite into martensite in hardened steels.


Levelling enables unwanted deformities in workpieces to be smoothed. Deformities can occur as the result of heat-treatment or forming processes. Our straightening presses are set up for processing long cylindrical workpieces.

Blasting and grinding

Our blasting and grinding plants are used principally to improve the surface of the component. We have dry and wet blasting units – which are operated using aluminum oxide – and two grinding units.
