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

Suitable flux: BF 38SD
Flux type suitability is strongly dependent on its application. In combination with the wire electrode the most suitable flux should match the requirements of the plate material as closely as possible under the existing welding conditions. Further information can be obtained from the technical flux data sheets.
