Quenched and Tempered is the quench hardened and then tempered that consists of a two-stage heat-treatment process. Stage one includes hardening, in which the steel is austenitised to approximately 900°C and then quickly cooled with water or oil. Stage two consists of tempering the material to obtain the desired material properties. One of the main advantages of tempering over quenching is that it helps to improve the toughness of the material without making it too hard. One of the main advantages of quenching over tempering is that it helps to harden the material, making it more resistant to wear and tear.
