3, SKD61 Heat Treatment:
Quenching:
The first stage of preheating:500 ~ 550 oC
The second stage of preheating:750 ~ 800 oC
Cooling or high pressure gas cooling, 100 ~ 150 oC in the tempering furnace.
Tempering:
Preheat:300 ~ 350 oC
Tempering heating:550 ~ 680 oC
Air cooling to room temperature, tempering three times.
