What is Super Duplex Steel Filler Wires?

These Super Duplex Steel Filler Wires are made up of chromium (24–26%), nickel (6–8%), molybdenum (3–4%), nitrogen, and iron, creating a dual-phase microstructure of austenite and ferrite. This special blend provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich or acidic settings. The wires boast impressive mechanical strength, with tensile strengths typically ranging from 110–125 ksi and yield strengths exceeding 80 ksi. Their high impact toughness and weldability, even in thicker sections, make them perfect for joining dissimilar or thick-walled components under demanding service conditions.
