Super Duplex Steel Welded Tubing typically features around 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, all of which enhance its strength and resistance to corrosion. Its dual-phase (ferritic-austenitic) structure provides high tensile strength (about 750 MPa) and yield strength (around 550 MPa). These welded tubes are particularly resistant to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich environments. Even with a longitudinal weld, our advanced welding processes guarantee excellent structural integrity and performance. Super Duplex welded tubing is a cost-effective choice for various industrial applications that require both strength and corrosion protection.
