ISO X 12 CrNi 17-7 Heat Treatments
- Tempering: Heated at 250°C to 450°C, held for 30 min to 24h, slowly cooled in the air.
- Hot forming: 1150-850°C, air cooling; Solution annealing (+AT): 1000-1100°C, water or air rapid cooling. 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%.
