Super Duplex Steel Tubing is mainly made up of about 25% chromium, 7% nickel, 4% molybdenum, along with trace amounts of nitrogen and manganese, resulting in a well-balanced austenitic-ferritic microstructure. This dual-phase design gives it remarkable strength and outstanding resistance to stress corrosion cracking, pitting, and crevice corrosion. Its mechanical properties boast a high tensile strength of around 750 MPa and a yield strength of about 550 MPa, with elongation values typically exceeding 25%. The tubing also shows good weldability and toughness, even in sub-zero temperatures, making it perfect for challenging operational settings.
