Xuan Nickel Alloys, one of Da Nang, Vietnam’s leading manufacturers and suppliers, excels in delivering high-quality Super Duplex Steel Coils. Designed to exhibit great strength, longevity, and better corrosion resistance, our coils are intended for the most arduous industrial applications. Featuring high molybdenum and chromium composition, these coils demonstrate excellent resistance to compression, pitting, erosion, and stress corrosion cracking. They find extensive application in offshore platforms for oil and gas, chemical processing, desalination plants, and marine environments, providing long-term performance in harsh conditions. At Xuan Nickel Alloys, we provide dependable, high-quality solutions specifically designed to suit your project requirements.
Super Duplex Steel Coils contain a precisely formulated combination of chromium, molybdenum, nickel, and nitrogen, which increases their corrosion resistance and stability. High chromium and molybdenum content generates high resistance to pitting, erosion, and stress corrosion cracking in chloride-contaminated environments. Mechanically, these coils possess very high tensile and yield strength, superior impact toughness, and high thermal and pressure resistance. Their high-strength structure provides durability, lower maintenance requirements, and consistent performance, even in harsh industrial environments. They are well suited for industries requiring strength, stability, and long life of service.

Super Duplex Steel Coils are extensively used in industries where there is an urgent need for superior strength and corrosion resistance. Within the oil and gas industry, they are utilized for offshore platforms, subsea equipment, and high-pressure seawater pipelines in harsh environments. Chemical processing industries also use them in storage tanks, heat exchangers, and reactors that process aggressive chemicals. Their high seawater resistance for this reason renders them suitable for use in desalination facilities and marine environments, such as in shipbuilding and subsea installations. They are also employed in power generation facilities, guaranteeing reliability under high temperatures and pressures. Their strength ensures safety and longevity in demanding industrial applications.
