Base Materials

Pipe steels acc. to ISO 3183, EN 10208 and API-5: L360N / X52 to L555Q / X80
suitable fluxes BF 6.30 and BF 6.5

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.

Package Forms

Coils, spools, drums and spiders as standard package forms for SAW-wire electrodes, different package forms on request.


2.0 – 5.0 mm; Sizes and tolerances acc. to ISO 544 and AWS A5.23.
