Neutral hardening

The hardening operation involves heating components above their phase transformation temperature and then quenching them in oil or salt baths, or in a specific gas quenching cell. This treatment results in a hard and tough martensitic or bainitic structure inside the components. Such operations can be carried out in a wide range of continuous or batch furnaces.
