Introducing examples of duplex stainless steel products! We can manufacture from raw materials to finished products according to your needs.
We have a track record of supplying materials for paper manufacturing and bridge components that require corrosion resistance, and we are also capable of producing raw materials such as forged and rolled materials. We have a research facility in Muroran, where we can respond to various needs, including material development and proposals for optimal processes. For example, in ultra-thick duplex stainless steel, the cooling rate slows down, causing the σ phase to precipitate and reducing ductility and corrosion resistance. However, through our original component design, it is possible to suppress the σ phase. We also have various machining equipment, allowing us to deliver not only simple round bar and pipe shapes but also components and parts in the shapes required by our customers. *For more details, please refer to the PDF document or feel free to contact us.

Compared to SUS304, the price is stable and lightweight design is possible. We have started selling stock for one size each of square pipes and angles.
Stainless steel is an alloy primarily made of iron, mixed with chromium, nickel, and other elements.
Due to the presence of chromium and other elements, a strong passive film forms on the surface, making it a corrosion-resistant metal. Stainless steel is not a rust-proof steel; it is a "rust-resistant" steel. As chromium is added to iron, it gradually becomes more resistant to rust. When more than 10.5% chromium is added, it is referred to as stainless steel. In addition to corrosion resistance, stainless steel possesses excellent properties such as heat resistance, workability, and strength. It also excels in aesthetics and is easy to maintain, which are significant features. Furthermore, stainless steel has a long lifespan, resulting in less frequent repairs and replacements, providing advantages in terms of lifecycle costs.
