GB 1J66 Heat Treatments


  • The first step: Heating to 1200°C, holding 3h, cooling to 600°C with a rate 100°C/h, then cooling to 400°C with a rate not less than 300°C/h; The second step: Tempering at 650°C in the transversal magnetic field in 16 x 104 A/m, holding 1h, cooling to 200°C with a rate 50-100°C/h.
  • Step 1:
    Heating temperature: 1200°C;
    Holding time: 3h;
    Cooling method: Cool at a rate of 100°C/h to 600°C, then cool at a rate of not less than 400°C/h to below 300°C, then remove from furnace.

    Step 2:
    Temper at 650°C in a transverse magnetic field of 1.6 x 104 A/m
    Holding time: 1h;
    Cooling method: Cool at a rate of 50 - 100°C/h to below 200°C, then remove from furnace.
