Super Duplex Steel Slitting Coils consist of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), Nitrogen (0.2–0.3%), and low Carbon (≤0.03%), the balance being Iron. This two-phase structure of this alloy makes it possess great mechanical strength, with tensile strength of 750–1000 MPa, yield strength of about 550 MPa, and elongation of about 25%. The material has a density of around 7.8 g/cm³, with high thermal conductivity and superior resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. With these characteristics, Super Duplex Steel is perfect for its application in aggressive environments that require high mechanical and chemical requirements.

Super Duplex Steel Slitting Coils find extensive application in industries where both strength and excellent corrosion resistance are demanded. Typical uses include heat exchanger fabrication, pressure vessel, and storage tank fabrication in petrochemical and chemical plants. They find applications in offshore oil rigs, desalination equipment, marine fittings, and paper and pulp machinery. The coils are particularly suitable for structural elements and welded structures in aggressive chloride-rich environments. Their elevated fatigue strength, weldability, and corrosion and erosion resistance render them a vital material in applications requiring reliability and durability under severe conditions.
