Annealing

After the hardening of steel it may be necessary, depending on the further use of the part, to anneal it as to counteract the tension of the material. The higher the temperature during annealing, the softer the steel gets. The hardness decreases, but the toughness increases.

In this case the induction heating method provides essential advantages: Both the temperature and the heating time can be accurately determined and adhered to. This ultimately leads to a high reproducibility and consistent part quality.
