The composition of Themba Nickel Alloys’ Duplex Steel 2205 Flanges includes iron (the balance), chromium (21%), nickel (5–6.5%), molybdenum (2.5–3%), along with trace amounts of nitrogen, manganese, and silicon. This unique mix gives the flanges remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in environments rich in chlorides and oxidizing agents. They boast impressive mechanical properties, with a tensile strength ranging from about 620 to 880 MPa and a yield strength between 450 and 620 MPa. Plus, they offer high toughness, ductility, and fatigue resistance, ensuring they hold up under extreme temperatures, pressures, and chemical exposure.
