Quenching normally refers to the controlled cooling of manufactured steel parts in a fluid to achieve desired metallurgical properties. A steel is quenched to increase it's hardness, strength and wear resistance. The process consists of heating and holding the steel at temperatures above 1200°C to disperse the carbon and alloying elements throughout the iron mass. At this temperature, the steel has an austenitic structure. If the steel is allowed to cool slowly, as in annealing, the structure is transformed to pearlite, a soft ductile mechanical mixture of ferrite and cementite. If the steel is cooled more rapidly, a harder martensitic structure is formed which consists of a solid solution of iron carbide in iron.
