Steels for quenching and tempering - Part 2: Technical delivery conditions for non alloy steels, EN 10083-2 / 1991

Heat Treatments

  • Austenitizing (quenching in water or oil): 820-860°C (30 min.); Tempering: 550-660°C 60 min.); Normalizing: 840-880°C (30 min.) The temperature at the lower end of the range are applicable to hardening in water, at the upper end for hardening in oil.
