MAXFLUX SAF-11
AWS: SFA 5.23 F8A2-EG-G
EN ISO CODE:
Maxflux SAF- 11 is an agglomerated special flux to weld 0.5Cr-0.7Ni-0.5Cu Weathering steels. The weld metal produces smooth beads and good slag detachability. The weld metal gives very less diffusible hydrogen (<5 ml/100gms. of W.M.).
Maxflux SAF-11 is suitable for single & multilayer welding of various weathering steels. Especially suitable for welding of Corten steels used in chemical, Petrochemicals and railway industries to resist atmospheric corrosion like ASTM steels: Grade ASTM A588Gr.A, B or C & A709 Gr.50W etc.
