AA-2594 is a flux cored wire designed for welding 25Cr type duplex stainless steels especially for Super Duplex grade, PRE (Pitting Resistance Equivalent) is over 40. Ar-CO2 mixed gas or 100%CO2 is recommended as shielding gas for excellent weldability.
Welding wrought, forged or cast super duplex stainless steels for service in the as-welded Condition. Heterogeneous welding between super duplex stainless steels and dissimilar welds between other stainless and mild or low alloyed steels.
