Hybrid surface modification treatment method "MM Process Type S" for sulfur immersion nitriding.
The power of wear resistance + solid lubrication! A composite treatment that generates nitrides and sulfides on the surface of steel materials.
The "MM Process Type S" is our proprietary technology that has been improved upon the MM process (sulfurizing nitriding). The "MM Process" enhances friction resistance by generating a lubricating sulfide on the surface of steel products, followed by a hard nitride. "Type S" further improves anti-seizing, anti-galling, and wear resistance compared to conventional methods by concentrating sulfur components in the sulfurizing nitriding layer. 【Features】 ■ The synergistic effect of the sulfide layer on the surface and the nitride layer formed inside provides heat resistance to the hardened layer. ■ It combines anti-seizing and wear resistance. ■ We accept test trials. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Matsuyama Giken Co., Ltd. is a company that contributes to society through surface treatment and heat treatment businesses. It started in 1970 as the Matsuyama Ski Industrial Cooperative Heat Treatment Plant and has launched new businesses over time to respond to various environmental changes and the diversifying needs of customers. Currently, it operates four business divisions: the heat treatment division that strengthens metals in various fields, the vacuum furnace division that improves the durability of molds using vacuum technology, the surface treatment division that protects various metals from rust, and the coating division that enables longer lifespans through surface modification of metals. By further combining these businesses, Matsuyama Giken is manifesting its strengths and responding to QCDS (Quality, Cost, Delivery, and Service). The future of manufacturing will increasingly rely on human sensitivity. We are committed to leveraging the technologies and skills we have cultivated so far in new manufacturing (and human development). We will continue to strive to meet our customers' expectations of "trust, safety, and anticipation."
