What are Annealing and Quenching? - Steel Rolling Mill Machine

An operation in which steel is heated above a critical point or recrystallization temperature for a period of time and then slowly cooled to a cooling rate less than that in still air is called annealing. After the steel is austenitized and rapidly cooled at a rate greater than the critical cooling rate, the supercooled austenite can be transformed into martensite. This operation is called ...
