Maxflux SAF-8 (PW) 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 desired from the
weld metal. The flux is neutral in Mn & Si pick up and especially designed to meet the
tensile & impact requirements after post-weld heat treatment condition up to 7
hours of holding at 620°C. The weld deposit is of radiographic quality.
Maxflux SAF-8 (PW) is suitable for single & multi-layer welding of high tensile
quenched & tempered steel, fine grained steels, heat resistant structural steels,
nuclear sector fabrication, etc.
Re-dry the flux at 300-350°C for two hours before use.
