Heat Treatment Processes Hardening. Hardening involves heating of steel, keeping it at an appropriate temperature until all pearlite is transformed into austenite, and then quenching it rapidly in water or oil. The temperature at which austentizing rapidly takes place depends upon the carbon content in the steel used.
Hardening - Heating the steel to the hardening temperature and cooling suddenly by quenching in an oil bath. Tempering - Reheating the hardened steel to the tempering temperature in order to relieve stress induced in the hardening process, and remove some of the hardness in exchange for toughness.
