Bristow Nickel Alloys, Midland, UK, is a reliable producer and supplier of high-quality nickel alloys and stainless steel products. We are specialists in offering tough, dependable solutions for oil and gas, petrochemical, and marine industries. Our Super Duplex Steel Flanges are highly resistant to corrosion, strong, and highly performing in aggressive environments. Best suited for high-temperature and high-pressure applications, these flanges provide the best reliability. We are dedicated to on-time delivery, making us a reliable business partner for your steel and alloy requirements.
Super Duplex Steel Flanges consist of about 25-30% chromium, 6-7% nickel, 3-5% molybdenum, and 0.2-0.3% nitrogen, which gives them increased strength and superior corrosion resistance. Mechanical properties are tensile strength up to 800 MPa, yield strength about 550 MPa, and high toughness. Physical properties are a density of 7.8 g/cm³, superior resistance to chloride stress corrosion cracking, and high pitting resistance. These flanges provide superior performance in extreme conditions and are, therefore, the best for oil and gas, marine, and chemical processing industry applications.

Super Duplex Steel Flanges are extensively applied in high-strength and corrosion-resistant industries. They are best suited for offshore oil and gas platforms, subsea pipelines, chemical processing, and marine environments. They are typically employed in pressure vessels, heat exchangers, storage tanks, and piping systems, especially in chloride stress corrosion-exposed environments. Their outstanding resistance to pitting and crevice corrosion qualify them for petrochemical, power generation, desalination, and other severe, high-pressure applications.
