Solid Wire Electrode BA-WIRE 320LR for Submerged Arc Welding
SFA 5.9 / AWS A5.9: ER320LR
BA-WIRE 320LR is a submerged arc welding wire intended for welding steels of similar composition in wrought and cast forms. BA-WIRE 320LR has composition similar to ER320, except that carbon, silicon, phosphorus and sulfur levels are kept at a lower level. The low melting residuals are limited in this alloy to reduce micro-fissuring. The weld metal provides exceptionally good corrosion resistance to a wide range of chemical environments.

ER320 stainless 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.
Coils, spools, drums and spiders as standard package forms for SAW-wire electrodes, different package forms on request.
