CSN 19 452 Heat Treatments

  • Forging at 1050 to 850°C, slowly cooling, eg in dry ash or oven.
    Soft annealing at 700 to 730°C, several hours of warming (by piece size), usually 4 hours and slowly cooling in the oven.
    Annealing to reduce stress at 600 to 650°C, 1 to 2 hours to warm up and slowly cool in the oven.
    Hardening in oil at 830 to 860°C.
    Tempering at 100 to 550°C, cooling down in the air, degree of tempering is controlled by the required hardness and toughness of the tool suitable spring hardness is about 45 to 55 HRC.
