ASME X1CrNiMoCuN20-18-7 Heat Treatments

  • Hot forming at 1200 to 1000°C, air cooling
    Solution annealing (+AT) at 1150 to 1200°C, air or water cooling. Cooling sufficiently rapidly in order to avoid the occurrence of intergranular corrosion.
    Solution annealing may be omitted if the conditions for hot working and subsequent cooling are such that the requirements for the mechanical properties of the product and the resistance to intergranular corrosion. If heat treatment is carried out in a continuous furnace, the upper part of the range specified is usually preferred, or even exceeded. Lower end of the range specified for solution annealing should be aimed at the 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% and a temperature of 1020°C for steels with Mo contents exceeding 3%.
  • Hot forming: 1150 to 850°C, air cooling; Solution annealing (+AT): 1140 to 1200°C, water or air cooling.
