Super Duplex Steel S32760 tube fittings are made of chromium (24-26%), nickel (6-8%), molybdenum (3-4%), and tungsten (0.5-1%), as well as nitrogen and copper for extra strength . They provide high tensile strength (750 MPa) and yield strength (550 MPa) with good corrosion resistance in high chloride environments. The fittings provide excellent mechanical properties such as rigidity and fatigue resistance. Their advantages include excellent resistance to pitting, crevice corrosion and stress corrosion cracking, making them ideal for offshore, marine and medical applications

Super Duplex Steel S32760 Tube Fittings are made up of a blend of chromium (24–26%), nickel (6–8%), molybdenum (3–4%), along with tungsten, copper, and nitrogen. This unique composition gives them remarkable resistance to pitting, crevice corrosion, and stress cracking. These fittings are known for their impressive mechanical properties, boasting high tensile strength, outstanding toughness, and minimal thermal expansion. They provide a yield strength that’s nearly twice that of regular stainless steel and remain stable over a broad temperature range. The duplex microstructure not only boosts strength but also enhances corrosion resistance, making them ideal for use in chloride-rich and highly corrosive environments.
