Solid Wire Rod BA-TIG 2594NL for TIG Welding
Classification:
EN ISO 14343-A: W 25 9 4 N L
SFA 5.9 / AWS A5.9: ER2594
Main Application
BA-TIG 2594NL is a solid wire rod for GTAW, suitable for welding Super-duplex stainless steels 2507 and other super-duplex stainless steels. The wire rod has excellent resistance to stress corrosion (SCC) in chloride-bearing environments and excellent resistance to pitting and crevice corrosion. BA-TIG 2594NL is also suitable for welding Duplex stainless steel grade 2205 and corresponding duplex steels when high corrosion resistance is required.
