Super Duplex Steel Coil Tubing is made up of about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, which creates a balanced ferritic-austenitic microstructure. This unique composition provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in environments rich in chlorides. It boasts a high tensile strength of around 750–800 MPa, a yield strength exceeding 550 MPa, and an elongation of 25–30%. The material’s impressive fatigue resistance, toughness, and weldability make it perfect for coiled installations that require both flexibility and structural reliability in harsh service conditions.
