Super Duplex Steel Tubing generally consists of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), Nitrogen (~0.2–0.3%), and Iron (balance), with trace elements like Copper (~0.5%), Tungsten (~0.5–1%), Manganese (<1.2%), and Carbon (<0.03%). This equiaxed structure provides enhanced resistance to chloride stress corrosion cracking, pitting, and crevice corrosion. The tubing possesses high tensile strength (~800 MPa), yield strength (~550 MPa), and elongation of about 25%. Having a density of 7.8 g/cm³ and thermal conductivity of ~15 W/m·K, it operates efficiently in high-pressure, high-temperature, and corrosive operating conditions.
