Improvement of mechanical strength and wear resistance! Salt bath soft nitriding treatment technology suitable for differential components.
We would like to introduce HEF's salt bath soft nitriding treatment technology suitable for differential components. The nitrided layers generated during the treatment (mainly the diffusion layer) improve mechanical strength and fatigue strength. Additionally, the compound layer formed during the treatment and its surface condition enhance wear resistance. The application and mass production of salt bath soft nitriding treatment for various differential components are progressing, and we have a track record of applications such as "application to differential cases" and "application to differential shafts." Please feel free to contact us when needed. 【Features】 ■ Improvement of mechanical strength ■ Improvement of wear resistance ■ Reduction of treatment costs (compared to electroless Ni plating) *For more details, please refer to the PDF materials or feel free to contact us.
