The composition of Duplex Steel S32205 Flanges from Themba Nickel Alloys includes a mix of iron (the balance), chromium (22%), nickel (5–6.5%), molybdenum (3%), along with trace amounts of nitrogen, manganese, and silicon. This unique blend gives them remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in environments that contain chlorides or are oxidizing. These flanges boast excellent mechanical properties, with a tensile strength ranging from about 620 to 880 MPa and a yield strength between 450 and 620 MPa. They also offer high toughness, ductility, and fatigue resistance, ensuring they perform reliably even under extreme temperatures, pressures, and chemical exposure.
