Super Duplex Steel S32760 Nuts consist of around 25% chromium, 7% nickel, 3.5% molybdenum, and nitrogen, tungsten, and iron additions, which make them higher in resistance against pitting, crevice corrosion, and chloride stress corrosion cracking. The duplex microstructure (austenitic-ferritic) confers excellent mechanical strength and fatigue life. These nuts have a tensile strength of ≥800 MPa, yield strength ≥550 MPa, and good impact toughness, even at cryogenic temperatures. Their high weldability, formability, and durability render them apt for application in critical components in high-pressure, high-temperature environments.
Super Duplex Steel Nuts S32760 are used widely in industries where mechanical reliability and corrosion resistance are critical. In the oil and gas industry, they are best suited for offshore platforms, subsea equipment, and refineries because of their chloride-induced stress corrosion resistance. In marine conditions, they are reliable in saltwater applications such as shipbuilding and propeller systems. They are applied to reactors, valves, pumps, and heat exchangers in chemical and petrochemical processing. They are also employed in power generation plants, desalination plants, and industrial equipment where their resistance guarantees structure stability as well as safety under harsh operating conditions.
