3. 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.Quenching temperature 1000 ~ 1050 degrees, 50 to 55 HRC hardness, heat treatment deformation is small, can be nitriding surface nitriding processing, processing of products has better wear resistance.
