MAXFLUX SAF -4 (UV) 5.23

AWS: SFA 5.23 F8A4/ P4-EA2-A2 & EA3-A3, F9A4/ P2-EF3-F3,F11A4/ F10P5-EN4-N4 EN ISO CODE: 14174 SA FB 1 76 DC

Maxflux SAF-4 (UV) is an agglomerated fluoride basic flux suitable to weld medium to high strength steels & low alloy steels. The weld made with this flux gives very low diffusible hydrogen content, good crack resistance and high sub-zero toughness properties. The flux provides uniform fusion in fillet welds & butt welds with excellent slag detachability. The flux can be used for multi-pass welding. The weld deposits are of radiographic quality and have less than 4ml diffusible hydrogen/ 100gms of weld metal.

Maxflux SAF-4 (UV) is suitable for single & multilayer welding of various structural, Boiler, Pressure vessel steels, Petrochemical industries, Refineries, Shipping, Quenched & tempered steel, heat resistant steels, Nuclear sector fabrications & other fabrication industries. 

Precaution

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