Enhance the surface of steel and achieve a deep and stable hardened layer! Introducing gas nitriding treatment!
"Nitriding treatment" is a surface hardening process that strengthens the surface of steel. Our company performs "gas nitriding treatment," which achieves a deep and stable hardened layer. It results in minimal thermal deformation and can significantly reduce the need for polishing. Often, it can be used without polishing. This process improves the material's fatigue resistance, and particularly, the high compressive residual stress of the nitrided layer significantly enhances the fatigue resistance of notched areas. 【Features】 - Surface hardening treatment that strengthens the surface of steel - Minimal thermal deformation, allowing for reduced polishing - High wear resistance, with almost no hardness reduction at temperatures up to 500°C - Sufficient corrosion resistance against superheated steam up to around 550°C - Low tendency for galling with counterpart materials in sliding parts - Gas nitriding has fewer environmental and health safety issues *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Features】 ■ The surface hardness of nitrided steel is very high, exceeding 1,000 in micro Vickers hardness, compared to approximately 800 for carburizing and high-frequency quenching. ■ Generally, alloying elements such as Cr, Al, and Mo are required for nitriding. ■ Surface hardness and hardening depth vary depending on the type of steel. ■ Nitrogen diffuses more widely into the core than the nitrogen compounds formed on the material surface, increasing the material's fatigue resistance and allowing for greater pressure resistance. ■ Hardening is possible within the range that gas can reach, making it easy to treat small gaps and inner diameters. ■ Gas nitriding is a relatively low-temperature treatment, allowing for the production of large processing furnaces and enabling the treatment of large components. *For more details, please refer to the PDF document or feel free to contact us.
