Effect of tempering temperature on microstructure and properties of high nitrogen stainless steel skates
The results show that when the tempering temperature is 180 ~ 550 °C, the hardness, tensile strength and yield strength decrease first, then increase and then decrease rapidly. The test steel reduces carbon and increases nitrogen, and there is no coarse eutectic carbide in the structure. When the…
