MAXFLUX SAF -8 (SPL )

AWS: SFA 5.17 F7A5-EL8

Maxflux SAF-8 (Spl) is an agglomerated fluoride-basic type flux suitable to weld medium to high strength steels where very low diffusible hydrogen content, good crack resistance and higher sub-zero toughness properties are required from the weld metal. The flux is neutral in Mn & Si pick up. The weld deposit is of radiographic quality and satisfies the NACE corrosion criteria of weld metal for HIC & SSC tests with Grade A (Spl) wire.

Maxflux SAF-8 (Spl) is suitable for single & multi-layer welding of high tensile quenched & tempered steel, fine grained steels, heat resistant structural steels, nuclear sector fabrication, etc. 

Precaution

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