Technical Explanation Document for Salt Bath Soft Nitriding "Tuftride Treatment / QPQ Treatment"

REACH regulation compliant! Reducing environmental impact with a unique salt bath agent. Also reduces disposal costs.

The "Tuftride treatment" is a salt bath soft nitriding process that uses a uniquely developed salt bath agent, compliant with the European environmental regulation "REACH." Compared to gas soft nitriding processes that use ammonia gas, it significantly reduces environmental impact. It offers many advantages in surface processing, such as improved wear resistance, corrosion resistance, and seizure resistance, and is adopted by major automobile manufacturers for shafts and ball screws, as well as by construction equipment manufacturers for hydraulic pistons. ★ We are currently offering a technical explanation document for free ★ [Contents of the document] ■ What is Tuftride treatment and QPQ treatment ■ Composition and thickness of the nitrided layer ■ Improvement of component characteristics and mechanical sliding properties ■ Plant technology ■ Consideration for the environment, etc. * The technical explanation document can be viewed via the download button below.
