MAXFLUX SAF -9

AWS: SFA 5.23 F8A5/A6-ENi2-Ni2, F8A5/A6-ECNi2-Ni2

Maxflux SAF-9 is an agglomerated fluoride-basic type flux suitable to weld with Autotherme Grade-H (ENi-2) & Autotherme Grade H(C) (ECNi2) wires for medium to high tensile strength steel, fine grained structural steels where very low diffusible hydrogen content, good crack resistance and higher sub zero toughness properties are desired from the weld metal. The weld deposit with these wires & flux is of radiographic quality.

Maxflux SAF-9 is suitable for single and multi-layer welding of high strength quench & tempered steel, ASTM 516 Gr.70 or Equivalent grade of steels, fine grained & heat resistance structural steels, nuclear sector fabrication etc.

Precaution

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