Super Duplex Steel pipe fittings consist mostly of alloys like UNS S32750 and S32760 that contain around 25% chromium, 7% nickel, 3–4% molybdenum, and nitrogen. All these factors account for high mechanical strength and better corrosion resistance, particularly against pitting, crevice corrosion, and stress corrosion cracking. Super Duplex provides high tensile strength of about 800–1000 MPa and yield strength of about 550 MPa. The duplex microstructure (ferrite and austenite) ensures better toughness and fatigue properties. These fittings also have great weldability and longevity in aggressive and high-pressure conditions.

Super Duplex Steel pipe fittings find extensive use in industries where corrosion resistance and high mechanical strength are essential. In offshore oil and gas production, they are employed in subsea piping, risers, and manifolds because of their superb resistance to seawater and chlorides. In chemical and petrochemical plants, they effectively deal with corrosive fluids and high pressure. They are also applied in desalination plants, heat exchangers, pressure vessels, and marine equipment. They can thrive even in harsh conditions and are therefore most suitable for safety-critical systems and long-term installations with minimum maintenance needs.
