MAXFLUX SAF -4 (UV)

AWS: SFA A5.17 F7A4/ P4-EH14, F7A5/ P5-EH10K 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 wdeposits 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.
