Tempering is the process of reducing or eliminating internal stress in quenched steel parts, or reducing their hardness and strength to improve their ductility or toughness. Tempering is a metal heat treatment process that involves reheating a quenched workpiece to an appropriate temperature below the lower critical temperature, holding it for a period of time, and then cooling it in a medium such as air, water, or oil.
