Vacuum gas nitriding treatment service

It can be applied to a wide range of steel types, and particularly in alloy steels containing more than 3% Cr, high hardness can be achieved.

Our company handles the technology of "Vacuum Gas Nitriding Treatment," which utilizes the diffusion principle of nitrogen atoms through a vacuum furnace. In a vacuum furnace, NH3 and nitriding-promoting gas are introduced, and the temperature is heated to 480-550°C. The heating state is maintained to allow nitrogen to diffuse into the base material, generating alloy elements and compounds as a surface treatment method. 【Features】 - No brittle white layer, preventing defects and peeling of the hardened layer - Minimal dimensional changes such as warping and expansion - Surface roughness remains almost unchanged from before treatment, achieving a good mirror finish - Excellent wear resistance - Uniform hardening even in complex shapes, deep holes, and fine wires, etc. *For more details, please download the PDF or contact us.
