Duplex Steel Coil Tubing is composed of a balanced mixture of austenite and ferrite, primarily containing elements like chromium (around 22–25%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), and nitrogen for enhanced corrosion resistance. It exhibits superior mechanical properties such as high tensile strength (up to 800 MPa), yield strength (around 550 MPa), and excellent fatigue resistance. The microstructure provides improved stress corrosion cracking resistance, making it suitable for high-pressure and corrosive environments.
