Xuan Nickel Alloys, a top-notch manufacturer and supplier in Da Nang, Vietnam, is renowned for its high-grade Super Duplex Steel Coils S32750. Specifically engineered for superior strength and outstanding corrosion resistance, the coils are made for long-lasting performance under adverse industrial conditions. With elevated chromium and molybdenum content, the coils possess excellent resistance against stress corrosion cracking, pitting, erosion, and compression. Ideal for offshore oil and gas platforms, chemical processing facilities, desalination plants, and marine engineering purposes, our S32750 coils promise long-lasting performance and durability. At Xuan Nickel Alloys, we stand by our promises to provide solid, efficient, and industry-standard solutions according to your requirements.
Super Duplex Steel Coils S32750 consist of about 25% chromium, 7% nickel, and 4% molybdenum, with strength and resistance boosted by nitrogen. Such a special chemical composition provides superior corrosion resistance in hostile and chloride-containing environments. Mechanically, they have high tensile strength, superior yield strength, and excellent impact toughness at high temperatures and pressures. Their two-phase microstructure (austenitic and ferritic) improves structural stability, weldability, and durability. These high strength properties render coils made from S32750 very suitable for applications demanding top-notch performance, low upkeep, and extended life in corrosive and harsh service environments.
