MAXFLUX SAF -8 (LS )

AWS: SFA 5.17 F7A2/P2-EM12K F7A6/P6/P8-EH10K EN ISO CODE: 14174 SA FB 1 67 DC

Maxflux SAF-8 (LS) is an agglomerated fluoride-basic type flux suitable to weld medium to high strength steels. The weld metal made with this flux gives very low diffusible hydrogen content, good crack resistance and higher sub-zero toughness properties. The flux is neutral in Mn & Si pick up and meets mechanical requirements after post-weld heat treatment at 620°C up to six hours of holding. The weld deposit is of radiographic quality. The weld metal passes the corrosion tests as per NACE standard TM-01-77 & TM-02-84.

Maxflux SAF-8 (LS) 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.
