Duplex Steel Tubing is crafted from a well-balanced blend of austenitic and ferritic stainless steels, typically featuring 22–25% chromium, 4–6% nickel, and 3% molybdenum. This unique composition offers remarkable resistance to stress corrosion cracking, pitting, and crevice corrosion. On the mechanical side, duplex steel boasts high tensile strength, generally ranging from 620–880 MPa, along with a superior yield strength of 450–620 MPa, all while maintaining good ductility and toughness. Its dual-phase microstructure ensures stability even at elevated temperatures and under high-pressure conditions, making it a durable and reliable option for structural and process applications in challenging environments, particularly in the chemical, petrochemical, and marine sectors.
