Super Duplex Steel Nuts usually consist of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), Nitrogen (0.2–0.3%), and Copper (0.5–1.0%), and Iron as balance and Carbon ≤0.03%. These nuts have very good mechanical properties, such as tensile strength of approximately 800 MPa, yield strength of 550 MPa, and elongation of approximately 25%. They also have a density of 7.8 g/cm³ and a melting range close to 1350°C. This composition provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich and severe industrial environments, and hence are suitable for high-load and corrosive applications.
