Improving wear resistance and fatigue resistance! It is also possible to nitride difficult-to-nitride materials that cannot be treated with gas nitriding.
The "Multi-Night Process (Gas Sulfurizing Nitriding Treatment)" is a technology that allows for the separate and flexible control of nitrogen and sulfur concentrations. It enables the nitriding of difficult-to-nitridize materials that cannot be treated with gas nitriding, improving seizure resistance and galling resistance, while the sulfurized layer (FeS, Fe-Xs) formed on the surface acts as a solid lubricant. Please use it for applications such as shims, thrust washers, engine timing gears, and the balls in ballpoint pens. 【Features】 ■ Separate and flexible control of nitrogen and sulfur concentrations ■ Improved seizure resistance and galling resistance ■ Enhanced wear resistance ■ Increased fatigue resistance ■ Improved pitching resistance *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Features】 - Prevents gear noise and improves peel resistance, among other effects. - The sulfide layer (FeS, Fe-Xs) formed on the surface acts as a solid lubricant. - The underlying hard nitrided layer plays a strong role in wear resistance. - The diffusion hardened layer from nitriding retains high compressive stress, enhancing fatigue strength. *For more details, please refer to the PDF document or feel free to contact us.
