(1), the processing temperature is low, the time is short, the workpiece deformation is small.
(2), not limited by steel, carbon steel, low-alloy steel, mold steel, stainless steel, cast iron and iron-based powder metallurgical materials can be soft nitriding treatment. The surface hardness of workpiece after soft nitriding is related to nitriding process and materials.
(3), can significantly improve the fatigue strength, wear resistance and corrosion resistance of the workpiece. It also has the properties of abrasion resistance and occlusal resistance under dry friction condition.
(4), because the soft nitrided layer does not have the brittle ξ phase, therefore the nitride layer has the certain toughness, does not easily flake off.
