Base Materials

Fine grain steels acc. to EN 10025, EN 10028: S620QL to S690QL
suitable flux BF 10

Pipe steels acc. to ISO 3183, EN 10208 and API-5: L625M / X90 to L690M / X100
suitable fluxes BF 6.30 and BF 6.5

Shipbuilding steels: high strength fine grain steels up to 690 MPa yield strength
suitable flux 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. Further information can be obtained from the technical flux data sheets.
