This process is then just called quenching and tempering ("strengthening"). When tempering at low temperatures, the steel retains a relatively high hardness and the steel is referred to as hardened steel (wear-resistant steel)! Tempering at relatively high temperatures leads to increased toughness with still increased strength!
