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.
Tool Steels are produced in the annealed condition for ease of machining. After machining, the steel is heat-treated and quenched depending upon the type of steel being used. The heat treating and quenching operations increase the toughness and strength of the material. There are three classes of tool steel generally available in the market today - cold work, hot work, and high speed steel: Cold Work steels have high strength, hardenability, impact toughness, and wear resistance.
