SS 142225: 1991 / Steel for hardening and tempering - SS-steel 22 25

Heat Treatments

  • Tempering: 840-870°C, cooling in oil and 820-850°, cooling in water; The steel should be tempered immediately after cooling. Tempering temperature (550-675°C) and holding time adapted to the dimension and the desired strength.
