Maxflux SAF-13 is a special flux used to weld structural steels. The Flux is specially designed to meet the tensile strength & Impact requirements. The weld metal produces smooth beads, good wetting, and excellent slag detachability. The weld metal gives very less diffusible hydrogen (<5 ml/100 gms. of W.M.).
Maxflux SAF- 13 is suitable for single & multilayer welding of various structural,
Boiler, Pressure vessel steels & other fabrication steels. It is suitable for welding of
ASTM steels: A387 Gr 11, 12, A182 F11, F12, A217 WC6,WC11, A234 WP11,
WP12, A199 T11 ASTM A387 Gr 21, 22 A234 WP22 A199 T21, T22 A200 T21, T22
& A213 T22A335 P22. etc.
Re-dry the flux at 300-350°C for two hours before use
