Duplex Steel Filler Wire is composed primarily of chromium (22–25%), nickel (5–9%), molybdenum (3–4%), and nitrogen, providing excellent corrosion and pitting resistance. This balanced dual-phase microstructure of austenite and ferrite ensures superior strength and toughness. The typical mechanical properties include a tensile strength of 750–850 MPa, yield strength around 550 MPa, and elongation of 25–35%. It maintains high resistance to stress corrosion cracking and exhibits excellent weldability, making it ideal for demanding applications in chemical, marine, and oil & gas industries.
