Quenching refers to the process of heating metal parts at a high temperature, maintaining their temperature, and letting them cool down immediately in a cooling medium (oil or water). Metal parts are reheated after quenching; toughness is improved during this process, which is called tempering. The strength obtained through quench hardening is not high, and metal parts are reheated to improve the toughness of the internal microstructure.
