NitridingFeature：Surface wear resistance, corrosion resistance, small deformation, suitable for high strength precise friction seal parts.

CarburizingFeature：Suitable for high load, high toughness of the heart, the surface of the wear-resistant parts or structures.

NormalizingFeature：Suitable for pretreatment of low carbon before nitriding.

Vacuum QuenchFeature：It is suitable for surface finish of high requirements, small deformation requirements, high precision tool steel or stainless steel.
