MAXFLUX SAF -5

AWS: SFA 5.17 F7A4-EM12K, F7A5-EH14, F7A5-EH10K

Maxflux SAF-5 is an agglomerated basic type flux for welding general structural steels, pressure vessel steels, pipe steels, micro-alloyed (BIS: 8500) & fine grained steels. Recommended to use with high Mn wires (like EM12K and EH14) for better impact properties. Slag detachability is good. Weld is of radiographic quality with very low diffusible hydrogen content.

Maxflux SAF-5 is suitable for single & multi-layer welding of structural welding, pressure vessels, boilers and other fabrications involving medium tensile & low alloy steel.

Precaution

Re-dry the flux at 300-350 C for two hours before use.
