Duplex stainless steel tubes, also known as DSS tubes, are a two-phase microstructure composed of austenite and ferrite. This unique structure provides duplex tubes with enhanced strength and excellent corrosion resistance, especially in harsh environments. Lean Duplex stainless steel tubes, a variation of the traditional duplex steel, contain a lower nickel content, offering a cost-effective solution while maintaining the core benefits, such as enhanced strength and excellent pitting resistance. The alloying elements in duplex steel typically include chromium, molybdenum, and nickel, with some containing nitrogen to further improve mechanical properties. They are also available in various grades such as UNS S32205, UNS S32750, UNS S32760, UNS S32304, UNS S32101, and Low Carbon UNS S32205L. Making it an ideal material for applications that require both strength and resistance to corrosion. Additionally, these tubes can reduce the overall nickel content without compromising performance.
