UNI X2CrNiMoN17-13-5 Heat Treatments

Solution annealed (+AT): 1100-1140°C (for guidance only), cooling sufficiently rapid in water or air.
Hot forming: 1150-850°C, air cooling;
+AT - Solution annealing: 1060-1140°C (If heat treatment is carried out in a continuous furnace, the upper part of the range specified should usually be preferred, or even exceeded). (The 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 %), air or water cooling; Cooling sufficiently rapidly in order to avoid the occurrence of intergranular corrosion.
