Base Materials

Fine grain steels acc. to EN 10025, EN 10028 and ASTM: P355ML2 / S355ML to P460ML2 / S460QL1 and ASTM A633 Gr. E
suitable flux BF 10

Nickel-Alloy steels 10Ni14 and 12Ni14
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.
