Super Duplex Steel 2205 Filler Wires typically feature around 22% chromium, 5–6% nickel, 3% molybdenum, and a balanced amount of nitrogen to enhance strength and corrosion resistance. This dual-phase austenitic-ferritic wire boasts excellent mechanical properties, including high tensile strength (usually between 750–850 MPa), good elongation, and remarkable toughness. It provides exceptional resistance to pitting, crevice, and stress corrosion cracking, particularly in chloride-rich settings. Designed for GTAW and GMAW welding processes, 2205 filler wires ensure stable arc performance, high weld integrity, and controlled ferrite content to preserve the ideal duplex microstructure in the weld deposit.
