Tempering is a heat treatment process used to reduce brittleness and improve the toughness of steel, as well as to relieve the stresses induced during the quenching process after hardening. It involves reheating the hardened steel to a temperature below its critical transformation range (typically between 150°C and 650°C), followed by cooling. This process allows the steel to achieve a balance between hardness and ductility. The material is heated to a specific temperature, held at that temperature for a designated period to refine its microstructure, and then cooled to attain the desired mechanical properties, including optimal hardness and toughness.
