Solid Wire Electrode BA-WIRE 385 for Submerged Arc Welding
EN ISO 14343-A: S 20 25 5 Cu L
SFA 5.9: ER385
BA-WIRE 385 is a submerged arc welding wire suitable for welding steels of similar composition of 20Cr/25Ni/4.5Mo/1.5Cu type (AISI 904L).
BA-WIRE 385 has high resistance to corrosion in severe, non-oxidising environments, sulphuric, phosphoric and other inorganic and organic acids, also good resistance to corrosion in concentrated nitric acid. Due to the low carbon, high alloy content of the wire the resistance to intergranular corrosion and stress corrosion cracking is increased, as well as a higher resistance to crevice and pitting corrosion when compared to standard grades AISI 304L and AISI 316L.
Suitable for some offshore applications, includingoverlays on mild and low alloy steels.

Suitable fluxes: BF 38, WP 380
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.
