PROPRIETARY DURIMPHY Heat Treatments

  • Annealing: 830°C/1-4h/rapid cooling.
    Annealing (small parts): 830°C/0.5-1h/rapid cooling.
    Solution annealing: 830°C/1-4h/rapid cooling.
    The rapid cooling prevents the retention of residual austenite.
  • The annealed condition is obtained following treatment at 830°C, cooling can be conducted at any rate, in other words without special precautions; Hardened treatment is 3 hours at 480°C; In causes the precipitation of intermetallic compounds. This precipitation treatment can be combined with work hardening.
