HEAT TREATMENT:
ANNEALING:
Heat the component slowly and uniformly to 800-810°C. Soak thoroughly for two to three hours and cool slowly in the furnace.
STRESS RELIEVING:
If the machining operations have been severe, we recommend stabilising just before the tool components are finish machined to relieve machining strains. Heat slowly to a temparature of 700°C, allow to cool in air.
HARDENING:
Preheat at 650°C followed by rapid increase of temperature to 900-950°C. Quench in oil. Tempering of this grade is always recommended after hardening.
TEMPERING:
Heat slowly to the required tempering temperature, soak thoroughly for two hours per 25mm section and allow to cool in air. For hot work applications, a minimum tempering temperature of 550°C should be used.
