Bristow Nickel Alloys in Midland, UK, is a prominent nickel alloys and stainless steel products manufacturer and supplier with an emphasis on quality. Our reliable solutions for industries like oil and gas, chemical, and marine are designed to deliver excellent results. Our Super Duplex Steel Nuts are made with high strength, excellent corrosion resistance, and great durability, thus perfectly suited for high-temperature, high-pressure operations. We provide punctual shipment of these high-performance nuts to deliver the most stringent demands in demanding industrial applications and to provide lasting reliability.
Super Duplex Steel Nuts consist of 25-30% chromium, 6-7% nickel, 3-5% molybdenum, and 0.2-0.3% nitrogen, offering outstanding corrosion resistance and strength. Mechanical properties have a tensile strength of up to 800 MPa, yield strength of approximately 550 MPa, and superior toughness. Physical properties have a density of 7.8 g/cm³, with superior resistance to chloride stress corrosion cracking, pitting, and crevice corrosion. These nuts are suited for high-pressure, high-temperature applications and are thus ideal for oil and gas, chemical processing, and marine engineering industries.
