MAXFLUX SAF-12

AWS: SFA 5.23 F8P2-EB6-B6, F8P2-EB2R-B2, F9P2-EB3R-B3, F9PZ-EB9-B9

Maxflux SAF-12 is an agglomerated special flux used to weld creep resistant steels. The weld metal possesses good CVN toughness combined with good strength. The weld metal produces smooth beads, good wetting, and excellent slag detachability. The weld metal gives very less diffusible hydrogen (<5 ml/100gms. of W.M.).

Maxflux SAF- 12 is suitable for single & multilayer welding of various structural, Boiler, Pressure vessel steels, Petrochemical industries, Refineries & other fabrication steels. It is suitable for welding of ASTM steels: Grade ASTM A213Gr.T5 A335 Gr.P5, A217 Gr.C5, A387 Gr11 & 12, A182 F11 & F12, A217 WC6 & WC11, A234 WP11 & WP12 A199 T11, A387 Gr 21 & 22 A234 WP22 A199 T21, T22 A200 T21, T22 A213 T22A335 P22, A 213 T91, A 335 P91, A 387 Gr 91, A 182 / A336, A 217 C12A, A 234WP91, A 369 FP91 etc.

Precaution

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