Base Materials

  • 9%Cr-1%Mo creep heat-resistant martensitic steels .
    ASTM: A182 F9, A199 T9, A200 T9, A213 T9, A234 WP9, A335 grade 9, A336 F9, A387 grade 9 DIN: X12CrMo 9-1, X7CrMo 9-1, GS-12CrMo 10-1.
    Suitable flux: 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.
