Duplex stainless steel (stainless steel alternative material) 【Ideal for water supply and drainage】

Duplex stainless steel (stainless steel alternative material) 【Ideal for water supply and drainage】

[New Stainless Steel Material] An alternative steel type to stainless steel. "Duplex stainless steel" with double the strength and excellent corrosion resistance.

Duplex stainless steel offers excellent strength and corrosion resistance, and it is a stable material in terms of cost. It is a new material that is currently attracting attention, particularly in the fields of water supply and drainage, and water treatment facilities, as an alternative to conventional stainless steels (SUS304, SUS316L). 【Features】 ● Ideal for seismic reinforcement ● Achieves lightweight components and cost reduction ● Equivalent corrosion resistance to SUS304 and SUS316L with "NSSC2120" and "S32304" 【Applications/Track Record】 ■ Lean duplex steel screens (gratings) adopted for stormwater outlets in sewage systems ■ Utilization of strength and corrosion resistance - Adoption as seismic reinforcement materials - Use in locations requiring high corrosion resistance - Cost reduction through lightweight design Alloy, as a pioneer in the stainless steel processing field, responds to all your needs from material supply to processing and technical support. Please feel free to consult us.

Contributing to the SDGs! Offering proposals and cost performance with a rich variety of products.

Contributing to the SDGs! Offering proposals and cost performance with a rich variety of products.

From lean duplex to super duplex, leave your duplex stainless steel needs to Yamato Special Steel!

Duplex stainless steel is a type of stainless steel that combines austenitic and ferritic structures. By leveraging its high strength and high corrosion resistance, it allows for value engineering (VE) from general-purpose stainless steel and other materials, increasing options. We have a rich inventory of duplex stainless steel, ranging from lean duplex to super duplex. 【Characteristics】 ■ High strength: Weight reduction ■ High corrosion resistance: Resistance to stress corrosion cracking and pitting corrosion ■ Low thermal expansion: Reduced maintenance burden and extended lifespan ■ Resource-saving: Reduction of rare metals With a low nickel content, it is less susceptible to fluctuations in material prices, contributing to sustainable consumption and production patterns, which aligns with the SDGs. *For more details, please refer to the PDF document or feel free to contact us.

Duplex Stainless Steel

Duplex Stainless Steel

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.
