Strip Electrode BA-STRIP 2594NL for Electroslag Overlay Welding

Classification:
EN ISO 14343-A: B 25 9 4 N L
SFA 5.9 / AWS A5.9: EQ2594

Main Application

BA-STRIP 2594NL is a strip electrode for electroslag overlay welding (ESW). Used to obtain a UNS S32760 / UNS 32750 corrosion resistant overlay on mild steel and low alloy steels. The overlay has excellent resistance to stress corrosion cracking (SCC) in chloride-bearing environments and excellent resistance to pitting and crevice corrosion.

Base Materials

Mild steels and low alloy steels.

Suitable flux: BF 44

Flux type suitability is strongly dependent on its application. In combination with the strip 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.

Package Forms

Coils or wound spools as standard package forms for strip electrodes.
