Heat Treatment 

Annealing:

 Generally, annealing adopts 780-800 degrees, heat preservation for 4-6 hours, cooling to 550 degrees at ≤50 degrees/hour, air cooling, isothermal annealing uses 700-800 degrees heat preservation 2-4 sales, and then 670-720 degrees heat preservation, keeping 2-4 hours, cooling to 500 degrees at a cooling rate of ≤50 degrees/hour, air cooling, annealing hardness 241-197H

Forging:

Oil-quenched die steel has some crack sensitivity. It is not suitable to heat rapidly during forging heating. It is best to perform a preheating at 650-750 degrees. The forging heating temperature is 1130-1150 degrees, and the final forging temperature should be greater than 800-850 degrees. The upper limit temperature is used when the steel ingot is forged. The lower limit temperature is taken when the blank is forged
