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
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
3Cr3Mo3W2V steel is suitable for making hot working dies such as upset forging and press forging. The service life of the mold is high.
