IS X01Cr20Ni18Mo6CuN Heat Treatments

  • Hot forming at 1200-1000°C, cooling in air.
    Solution annealing (+AT) at 1140-1200°C, rapidly cooling in water or air.
    The lower end of the range for solution annealing should be aimed at for heat treatment as part of further processing. Because otherwise the mechanical properties might be affected. If the temperature of hot forming does not drop below the lower temperature for solution annealing a temperature of 980°C is adequate as a lower limit for Mo-free steels, a temperature of 1000°C for steels with Mo contents up to 3%; a temperature of 1020°C for steels with Mo contents exceeding 3%.
  • Solution annealed at 1 140 to 1 200°C - If heat treatment is carried out in a continuous furnace, the upper part of the range specified is usually preferred, or even exceeded;
    Cooling in water, air - Cooling sufficiently rapidly in order to avoid the occurrence of intergranular corrosion as defined in IS 10461 (Part 2).
