Olwan Nickel Alloys, based in Amman, Jordan, stands out as a top manufacturer and supplier of high-performance stainless steel products, with a focus on Duplex Steel S31803 tubing. Known for its precision, durability, and commitment to international standards, Olwan Nickel Alloys crafts tubing designed for tough industrial, marine, and offshore environments. The Duplex Steel S31803 tubing is celebrated for its remarkable corrosion resistance, impressive tensile strength, and exceptional toughness, making it perfect for challenging conditions. Catering to sectors like chemical processing, oil and gas, power generation, and marine, the company employs cutting-edge manufacturing techniques and rigorous quality control to ensure that their tubing delivers reliable performance, longevity, and structural integrity.
Duplex Steel S31803 tubing is made up of about 22% chromium, 5–6% nickel, and 3% molybdenum, featuring a balanced ferrite-austenite microstructure. This unique composition grants it excellent resistance to chloride-induced corrosion, pitting, and crevice corrosion. On the mechanical side, the tubing showcases high tensile and yield strength, remarkable toughness, and solid fatigue resistance. The duplex microstructure guarantees dimensional stability, resistance to stress corrosion cracking, and superior mechanical performance even under high pressure and load. With its blend of durability and corrosion resistance, Duplex Steel S31803 tubing is perfect for critical industrial, marine, and offshore applications that demand both strength and long-lasting reliability.
