Heat Treatment
DIN 1.2379 steels alloy should be preheated very slowly to 815℃ (1500°F) and the temperature can be increased to 1010oC (1850°F). Then held at 1010oC (1850°F) for 20 to 45 minutes and air-cooled (air quenched).

 

Annealing
Annealing of 1.2379 tool steels material should be done at 871 to 898°C (1600 to 1650°F) followed by slow furnace cooling at 4.4°C (40°F) per hour or less, after which cooling rate could be increased. At the same time, must do something to prevent excessive carburization or decarburization.
