Maxflux SAF-704 is a fluoride-basic type flux suitable to weld with composite SAW wires. The flux is neutral in nature and is also suitable with all HF (Hard Facing) class wires. The deposited weld metal has low diffusible hydrogen content and crack resistant during hard surfacing.
Maxflux SAF-704 flux suited with composite SAW wires. With ECNi2 wire the weld
metal gives excellent mechanical and charpy V notch impact properties (40-70J at -
51ºC). For hard surfacing application on steel mill rolls, the flux is suitable with
Maxfil HF-20,Maxfil HF-30,Maxfil HF-45 &Maxfil HF-55wires depending upon the
composition & hardness requirement. Recommended welding procedure shall be
followed as in our product literature
