Super Duplex Steel Threaded Rods are designed to excel in tough, corrosive industrial settings. Made from high-quality super duplex stainless steel grades like S32750 or S32760, these rods offer remarkable strength, durability, and resistance to corrosion caused by chlorides. Thanks to their unique duplex microstructure, they boast impressive mechanical properties, making them perfect for high-pressure and high-stress situations. With their excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, Super Duplex Threaded Rods are a go-to choice in offshore, marine, chemical, and desalination industries. They provide dependable fastening solutions where long-lasting stability and top-notch corrosion resistance are crucial.
Super Duplex Steel Threaded Rods are crafted from a well-balanced blend of chromium (24–26%), nickel, molybdenum (3–5%), and nitrogen, which together ensure outstanding corrosion resistance and mechanical strength. Their duplex austenitic-ferritic structure grants them high tensile and yield strength, excellent fatigue resistance, and enhanced toughness. These rods effectively resist pitting and crevice corrosion in environments rich in chlorides and maintain their stability even at high temperatures. With remarkable resistance to stress corrosion cracking and erosion, Super Duplex threaded rods promise long-lasting performance in demanding, high-pressure conditions, making them ideal for critical industrial applications that require maximum strength and durability.
