Super Duplex Steel Angles are made up of about 25% chromium, 7% nickel, 3–4% molybdenum, and nitrogen, which boosts their resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. These angles boast impressive mechanical properties, including a tensile strength of 800–900 MPa, a yield strength of around 550 MPa, and an elongation of 25–30%. They also provide good impact toughness and weldability, even in freezing temperatures. The duplex structure offers a well-balanced mix of strength and corrosion resistance, making these angles ideal for load-bearing applications in aggressive and high-pressure settings.
