CSN C25 Heat Treatments


  • Hardening: 860-900°C (Temperatures at the lower end of the range are generally used for water, and those at the upper end for oil quenching. Time for austenitizing as a guide: at least 30 min.);
    Quenching agent: Water (Other quenching agents such as synthetic quenchants may also be used.);
    Tempering: 550-660°C (Time for tempering as a guide: at least 1h.);
    Normalizing: 880-920°C.
  • Austenitizing (quenching in water): 860-900°C, t > 30 min. Tempering: 550-660°C, t > 60 min. Normalizing: 880-920°C, t > 30 min.
