Carburizing
Carburizing quenching and tempering are performed mainly for steel tapping screws. Screws for precision instruments (micro screws, camera screws, and micro screws) can be also processed in Saitama.
Application
Tapping screws for construction and No. 0 screws for weak electric current
Non-oxidation Quenching and Tempering (Thermal Refining)
Non-oxidation quenching and tempering are performed for bolts of small to large sizes.
Application
Automotive bolts
Vacuum thermal treatment (for stainless steel)
Suitable vacuum quenching (bright quenching), vacuum nitriding treatment, and a solution treatment are performed for small mass-produced products and precision parts. The treatment increases intensity as well as brilliance.
Application
Tapping screws, drill screws, and mesh products
Solution thermal treatment
Solution thermal treatment is suitable for austenitic stainless steel. The treatment prevents not only corrosion resistance degradation due to deposits but also cracks generated after riveting.
Application
Tapping screws, drill screws, and mesh products
Metal thermal treatment technician
We are committed to training our engineers to provide high-quality services to our customers with the latest technology and knowledge.
