[0002] Quenching is a heat treatment process. In the process of steel production and processing, quenching is a heat treatment process that heats the steel to a temperature above the critical temperature, keeps it warm for a period of time, makes it fully or partially austenitized, and then rapidly cools it to below Ms at a cooling rate greater than the critical cooling rate to perform martensitic transformation. By combining tempering at different temperatures, the rigidity, hardness, wear resistance, fatigue strength and toughness of the steel can be greatly improved, thereby meeting the different use requirements of various mechanical parts and tools.
