8. Heat treatment:
Quench:1000-1040`C via 600`C and 850`C, preheating oil or wind cooling
Temper temperature and rigidity HBC(reference) quench
hardening 108-300`C 450-500`C 550-5700`C
53-55 51-52 53-54 50-52
Temper temperature should be higher than working temperature in order to stabilize the
working size of mold.
Heat up to 650`C of average temperature in order to eliminate themachined stress, 500` air cooling after electric cooker cooling
Tempering, 800-850`C,slow cooling after diathermia.
