Ashraf Nickel Alloys stands out as a reliable manufacturer and supplier of Super Duplex Steel Tube Fittings in Riyadh, Saudi Arabia. We provide top-notch solutions for industries that operate in harsh and corrosive environments. Our tube fittings are designed to create leak-proof, high-pressure connections and are built to endure the toughest service conditions found in chemical processing, oil & gas, and marine sectors. Adhering to ASTM, ASME, and ISO standards, they boast impressive mechanical strength, corrosion resistance, and durability. With a range of sizes, end connections, and pressure ratings, our Super Duplex tube fittings ensure exceptional reliability in both high-temperature and cryogenic applications, promising long-lasting, maintenance-free performance.
Super Duplex Steel Tube Fittings are made up of about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, which together provide outstanding corrosion resistance and strength. These fittings deliver a yield strength of around 550 MPa and a tensile strength of 800 MPa, making them much stronger than regular stainless steels. With a PREN greater than 40, they are highly resistant to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. They also offer excellent fatigue resistance, high toughness, low thermal expansion, and remarkable weldability, making them the perfect choice for high-performance fluid and gas transfer systems in demanding industrial settings.
