Tempering or hardening of steel is a heat treatment to which steel is subjected to increase its hardness, flexibility, elasticity and resistance to stress. The process is carried out by heating the steel to a temperature of approximately 915°C in which the ferrite is converted into austenite, then the steel sheet is rapidly cooled by immersing or spraying it in water, oil or other fluids or salts that act as a coolant.
