MAXFLUX SAF -7X
AWS: SFA 5.17 F7AZ-EL8, F7A0-EM12K
EN ISO CODE:
Maxflux SAF-7X is an acidic flux for longitudinal & spiral high speed pipe welding applications. 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-7X is suited for fabrication and welding of longitudinal pipe, spiral pipes, penstock pipelines, wind mill towers, pressure vessels, girder, earthmoving equipment, structures of off-shore platforms, etc.
