The Super Duplex Steel Nuts S32750 are made up of around 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, which significantly boost their mechanical strength and corrosion resistance. They boast impressive tensile strength ranging from 800 to 1000 MPa, with yield strength nearly twice that of standard austenitic stainless steels. Even in sub-zero temperatures, these nuts maintain excellent toughness and ductility. Their advanced alloy composition provides robust resistance to chloride-induced stress corrosion cracking, localized corrosion, and erosion, making them a reliable choice for fastening in demanding industrial settings.
