3, SKD61 Heat Treatment:
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.
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.
4, SKD61 Hardness: annealing 235 ~ 205 HB, quenching ≥50 HRC
