Products Available
| Products Available | Characteristics |
|---|---|
| Stainless steel for springs | Features the strong work-hardening properties of austenitic stainless steel. Typical grades are 301, 304, and 631, which can be finished to suit the specified hardness. |
| Ultrathin stainless steel | We offer a wide range of ultrathin stainless steel types, including 301, 304, 430, and 631, manufactured as ultrathin foil, down to thicknesses of 8 µm. |
| Stainless steel for etching | The steel undergoes tension annealing to improve flatness, making it ideal for etching. |
| Surface treated stainless steel | The steel undergoes electropolishing and chemical polishing for improved designability and performance. |
| Non-magnetic stainless steel | Retains its non-magnetism even after extreme cold-working. |
| Stainless steel for gaskets | Features a finer crystalline structure to maintain high spring performance and fatigue characteristics. |
| High-strength stainless steel | We offer stainless steel that’s been cold-worked to a hardness of HV530 or more and precipitation-hardened stainless steel heat treated after forming for increased hardness. |
| Stainless steel for automotive molding | This ferritic steel offers superior mirror finish characteristics compared to BA, and corrosion resistance equivalent to 304 steel. |
| General purpose stainless steel (sheet/bar) | We offer various grades, including 304, 316, and 316L. As a primary trading company, we can procure materials from various companies in Japan, as well as offer lower cost solutions in the form of products sourced from overseas suppliers. |
| Hydrogen-resistant stainless steel | Maintains durability even at extremely low temperatures and high pressures. |
| Duplex stainless steel | Combining the characteristics of both austenitic and ferritic steel makes it possible to reduce thickness—and thereby reduce costs—while continuing to offer excellent corrosion resistance. |
