quenching

Quenching steel results in transformation of austenite into martensite, it is not completely transformed. There are some of the crystals of austenite that remain unchanged and are not affected by quenching below martensite-finish temperature. This can further be transformed into martensite, through slow cooling of the metal at extremely lower temperatures. Normally, cold treating includes […]

Heat treating is a process of heating or cooling metals and is used to alter their properties in order to obtain the desired shape and structure such as brittleness, hardness, and softness. The steps for achieving these things are consistent with all heat treatment processes. Heat treatment techniques include annealing, tempering, hardening, quenching, stress releasing […]
