Abrafil S3Si UP

Wire electrode with higher Si-content for submerged arc welding of non-alloy and fine grain steels (especially Off-Shore), higher strength shipbuilding steels, pipe steels, boiler and vessel steels.

suitable fluxes BF 3, BF 5.1, BF 6.5 and BF 10

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.
