Base Materials

Fine grain steels acc. to EN 10025, EN 10028 and ASTM: P420N / S420NL / A633 Gr. E and P460N / S460NL
suitable fluxes BF 3, BF 4, BF 5.1, BF 6.5 and BF 10

Pipe steels acc. to ISO 3183, EN 10208 and API-5: L415N / X60 to L485Q / X70
suitable fluxes BF 5.1, BF 6.30 and BF 6.5

Heat-resistant steels acc. to EN 10028 and ASTM: 16 Mo 3 / A204 Gr. A and A209 Gr. T1, S275J2G3 / A572
Gr. 42 and S355J2G3 / A572 Gr. 50
suitable fluxes BF 1, BF 3, BF 4, 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. Further information can be obtained from the technical flux data sheets.
