Base Materials

Surfacing: all weldable backing materials, unalloyed and low-alloyed.
Joining: corrosion resistant Cr-steels as well as other similar-alloyed steels with C-contents up to 0.20 %.
1.4510 X3CrTi17
AISI 430 Ti; AISI 431

Suitable fluxes: BF 38, WP 380

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.
