Super Duplex Steel Nuts are made from a distinctive dual-phase microstructure that combines ferritic and austenitic stainless steel, infused with about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen. This unique blend boosts their resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. They boast high tensile and yield strength, making them tougher than regular stainless steel nuts. Plus, these nuts retain excellent toughness and ductility, even in low temperatures. Their mechanical stability, paired with exceptional corrosion resistance, guarantees long-lasting performance and reliability in demanding industrial settings, making them ideal for critical fastening tasks.
Super Duplex Steel Nuts find extensive application in industries that require exceptional strength and corrosion resistance. They are crucial components in offshore oil and gas platforms, subsea equipment, and marine applications where resistance to seawater is vital. The chemical processing and petrochemical sectors utilize them in machinery and piping systems that face harsh chemicals and acids. Additionally, they are essential in desalination plants, heat exchangers, and power generation facilities. The construction and heavy engineering industries also depend on these nuts for their robust performance in various applications.
