About 23% chromium, 7% nickel, 3.5% molybdenum, and 0.2% nitrogen are normally present in Super Duplex Steel ER2307 Welding Wire, which is balanced with iron and trace amounts of manganese and silicon. For improved strength and corrosion resistance, this composition offers a favourable austenite-ferrite microstructure. The wire has good ductility with elongation above 25%, a yield strength of about 500 MPa, and a tensile strength of about 700–850 MPa. Because of its exceptional weldability, high toughness, and resistance to stress corrosion cracking, ER2307 is a good choice for demanding structural and pressure-bearing welds.
