Quenching and tempering consists of a two-stage heat treatment process. The first stage involves hardening, where the steel is heated up to 900°C and austenitized and then rapidly cooled with water or oil. The second stage consists of tempering the material to obtain the desired material properties. This process provides to obtain a fine-grained and homogeneous microstructure. Quenched and Tempered steels are characterized by high strength and good ductility.
