What sets Themba Nickel Alloys’ Super Duplex Steel Bars apart is their unique microstructure, which is about 50% austenite and 50% ferrite. This balance gives them exceptional strength and corrosion resistance. With a composition rich in chromium (24–26%), nickel (6–8%), and molybdenum (3–5%), these bars are highly resistant to pitting, crevice corrosion, and stress corrosion cracking. They also feature impressive yield strength (around 550–650 MPa) and tensile strength (approximately 850–950 MPa), along with good toughness and fatigue resistance. This combination of mechanical and chemical properties ensures they last in even the most corrosive and demanding industrial settings.
