Forming a hard and lubricative sulfur-nitride layer! A surface modification technology that improves wear resistance and more!
"Gas Nitriding with Sulfur (Multinight)" is a surface modification technology that has been independently developed by our company, building on our multi-purpose gas nitriding method. The formation of a hard and lubricating sulfide-nitriding layer demonstrates excellent effects in improving wear resistance, seizure resistance, galling resistance, fatigue resistance, and corrosion resistance. 【Features】 ■ Good working environment, pollution-free processing ■ Improved seizure resistance, galling resistance, and wear resistance ■ Reduction of gear noise, deformation, and dimensional changes ■ Controllable concentrations of N and S ■ Gas consumption is about half that of gas soft nitriding *For more details, please refer to the PDF document or feel free to contact us.
