What is Duplex and Super Duplex Steel Flux Core Wire?

These Flux Core Wires feature a well-balanced austenitic-ferritic microstructure and are enriched with chromium (22–26%), nickel (5–9%), molybdenum (3–4%), and nitrogen, which gives them impressive resistance to pitting, crevice corrosion, and stress corrosion cracking. Common grades include E2209T1-1/4 for Duplex and E2594T1-1/4 for Super Duplex. They boast high tensile strengths (usually between 95–125 ksi) and remarkable impact toughness, even in freezing temperatures. The flux core design allows for deeper penetration, quicker deposition rates, and better arc control, making them perfect for welding thicker materials while minimizing downtime and spatter.
