Victor Nickelalloys, a well-respected manufacturer and supplier located in Abuja, Nigeria, specializes in top-notch Super Duplex Steel Tubing that’s built to deliver exceptional strength, corrosion resistance, and durability in even the toughest environments. These tubes are crafted using cutting-edge production methods and high-quality super duplex stainless steel, ensuring they perform excellently and with precision. Renowned for their ability to resist pitting, crevice corrosion, and stress corrosion cracking, the Super Duplex Steel Tubing from Victor Nickelalloys is perfect for applications in the chemical processing, marine, oil & gas, and desalination sectors. Each tube is designed to meet international standards, guaranteeing long-lasting reliability and performance, even under extreme conditions.
Super Duplex Steel Tubing features a unique dual-phase microstructure of austenite and ferrite, typically comprising chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and trace amounts of nitrogen. This special blend offers remarkable corrosion resistance and improved mechanical properties. The tubing boasts a tensile strength of around 800–1000 MPa, a yield strength of 550 MPa, and outstanding resistance to chloride-induced stress corrosion. It also showcases excellent weldability, toughness, and fatigue strength, even in low-temperature settings. The combination of high strength and corrosion resistance makes Super Duplex Steel Tubing a smart and durable choice for aggressive environments.
