The Process of hardening and Temperings involves heating the steel strip to above the critical transformation temperature for the given grade and then rapidly cooling through quenching. Then Steel requires further treatment in the form of tempering. This consists of reheating the steel strip to a lower temperature and holding it at the given temperature for a given period of time. This process is done in an inert atmosphere to avoid oxidation.
