What sets Themba Nickel Alloys’ Super Duplex Steel Fasteners S32760 apart is their unique microstructure, which consists of about 50% austenite and 50% ferrite, along with a rich blend of chromium (25–26%), nickel (6–7%), and molybdenum (3–5%). This special composition gives them outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. Plus, these fasteners boast high tensile strength (850–950 MPa) and yield strength (550–650 MPa), all while maintaining excellent toughness, impact resistance, and long-lasting durability. These features ensure that fastening remains secure and reliable, even in high-temperature, high-pressure, and chloride-rich environments.
