For improving the wear resistance, fatigue strength, and sliding performance of steel materials, gas soft nitriding treatment is recommended.
This is an introduction to the gas soft nitriding treatment (SN process) conducted by our company. When gas soft nitriding is performed, a compound layer (ε layer) of about 5μm to 20μm is formed on the metal surface. This compound layer consists of a layer made of nitrides and carbides, and the gas soft nitriding treatment is conducted in an atmosphere that contains not only nitrogen atoms but also carbon atoms. Furthermore, inside this compound layer, a layer of nitrides called the diffusion layer is formed, and these compound and diffusion layers enhance the wear resistance, fatigue strength, and sliding performance of steel material components. For this reason, it can be said that this is a widely used surface heat treatment for automotive parts, electronic components, general industrial equipment, molds, and more. 【Features】 ■ Shapes that are unsuitable for salt bath nitriding or plasma nitriding, such as deep holes and slits, can be easily treated. ■ The surface has a clean, milky white finish without the adhesion of impurities or oxide films. ■ Easily applicable from small lots to mass production, for both small and large parts. ■ Improvement of mechanical properties: enhanced wear resistance (effect of high hardness and low friction coefficient of the compound layer). *For more details, please refer to the PDF document or feel free to contact us.
