DIN 1.1337 Heat Treatments
- Normalization: 880 to 940°C, cooling in stationary air after the temperature has been reached over the entire cross section; Austenitization: 880 to 940°C, Cooling in oil or water. This treatment shall be employed for relatively large heat-treatment wall thicknesses, in order to be able to maintain the minimum temperature of 640°C for tempering; Tempering at 610 to 680°C; Stress-relief annealing: 530 to 580°C. For multiple stress-relief annealing steps, the indicated temperature range shall be applicable for the last stress-relief annealing step. Preceding stress-relief annealing steps can be performed at 530 °C to 570°C.
