A633 Gr. E
Suitable flux: BF 5.1

Pipe steels acc. to ISO 3183, EN 10208 and API-5: L360M / X52 to L415M / X60
Suitable fluxes: BF 6.30, BF 6.5

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.
