Home >Super Duplex Steel Nuts S32760
Super Duplex Steel S32760 Nuts are top-notch fastening components crafted for the toughest industrial environments where outstanding corrosion resistance and mechanical strength are a must. Made from Grade S32760 super duplex alloy, these nuts are a popular choice for marine, offshore, chemical, and oil & gas applications. Thanks to the alloy’s remarkable resistance to pitting, crevice corrosion, and chloride stress-corrosion cracking, they promise long-lasting reliability even in the harshest conditions. With their impressive toughness and durability, Super Duplex S32760 Nuts provide a trustworthy fastening solution for high-pressure and high-temperature systems, supporting essential equipment like pumps, valves, flanges, pressure vessels, and structural assemblies.
Super Duplex Steel S32760 Nuts are crafted from a well-balanced ferritic-austenitic alloy that includes around 25% chromium, 7% nickel, 3.5% molybdenum, along with added tungsten and nitrogen to enhance corrosion resistance. This unique blend gives them remarkable strength, high hardness, and exceptional resistance to chloride-induced cracking. Compared to regular stainless steels, this alloy boasts very high tensile and yield strength, along with outstanding impact toughness. Its dual-phase structure ensures stability at elevated temperatures and excellent performance in aggressive environments, making S32760 nuts perfect for heavy-duty and safety-critical industrial applications.
