AWS: SFA 5.17 F7AZ-EL8, F7A0-EM12K

EN ISO CODE:

Maxflux SAF-7S is a high speed welding acidic agglomerated flux for spiral pipe welding. The flux is suitable for single & multi-pass welding with single wire & multi-wire applications in both AC & DC polarity. Slag detachability is good and deposited weld metal is of radiographic quality.

Maxflux SAF-7S is suited for fabrication and welding of spiral pipes, smaller diameter pipes (internal and external), penstock pipelines, wind mill towers, pressure vessels, girder, earthmoving equipment, structures of off-shore platforms, etc.
