Super Duplex Steel S32760 is an advanced alloy containing approximately 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, with additions of tungsten and copper. Excellent strength and resistance to corrosion are provided by this balanced dual-phase (austenitic-ferritic) microstructure. It has a high yield strength of about 550 MPa, a high tensile strength of about 750 MPa, and an elongation of about 25%. The alloy maintains exceptional toughness and durability in demanding industrial applications while excelling in resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in environments that are chloride-rich and maritime.

Super Duplex Steel S32760 Bolts are in high demand for applications requiring remarkable mechanical strength and resistance to corrosion. Because they are resistant to stress corrosion caused by seawater and chloride, they are widely utilised in heat exchangers, desalination plants, offshore oil and gas platforms, and subsea equipment. Additionally, because aggressive media are frequently used in pulp and paper industries, pressure vessels, chemical processing facilities, and structural assemblies, these bolts are perfect. They are a popular option for demanding applications in both onshore and offshore engineering projects because of their resilience in high-pressure and high-temperature environments, which guarantees dependable fastening in crucial systems.
