Ashraf Nickel Alloys stands out as a reliable manufacturer and supplier of Super Duplex Steel Tubing S32760 in Riyadh, Saudi Arabia. We provide top-notch solutions for industries that require exceptional corrosion resistance and mechanical strength. Also known as UNS S32760, this super duplex stainless steel is renowned for its remarkable resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Manufactured to comply with ASTM A789/A790 and ASME standards, our products guarantee precision, reliability, and high performance in critical applications. Our seamless and welded tubing is perfect for marine, oil & gas, and chemical industries, boasting impressive durability, weldability, and a long service life even in harsh environments.
Super Duplex Steel S32760 Tubing is made up of about 25% chromium, 7% nickel, 3.6% molybdenum, along with tungsten additions and nitrogen to maximize corrosion resistance. It achieves a tensile strength of around 800 MPa and a yield strength of about 550 MPa, nearly double that of standard austenitic grades. The alloy’s unique austenitic-ferritic microstructure boosts toughness, fatigue resistance, and protection against stress corrosion cracking. With a PREN greater than 40, it’s specifically engineered for high-stress, chloride-rich environments. S32760 is ideal for high-pressure and high-temperature applications, offering excellent dimensional stability, low maintenance, and outstanding resistance to erosion and localized corrosion.
