Super Duplex Steel Tubing typically consists of 24–26% chromium, 6–8% nickel, 3–4% molybdenum, and nitrogen, which together provide exceptional corrosion resistance compared to regular stainless steels. In terms of mechanical properties, it boasts nearly double the strength of austenitic grades, along with excellent tensile strength, fatigue resistance, and durability. Super Duplex Tubing is dependable under high pressure and in environments laden with chlorides, seawater, and aggressive chemicals. It also retains its toughness at both low and high temperatures. With outstanding weldability and long-term stability, Super Duplex Steel Tubing is perfect for critical applications that require high performance and corrosion resistance.
