OK Flux 10.70      SAW

Type Basic

OK Flux 10.70 is specially designed for welding with OK Autrod 12.10 and OK Autrod 12.20 in the butt and fillet welding of mild, medium and high tensile steels with impact requirements down to -20C. OK Flux 10.70 is of the aluminate basic type and has very high current-carrying capacity on both AC and DC for this slag system. As it is an alloying flux with significant Si and Mn pick-up, it is most suitable for applications in which the dilution of base material is high - in other words, in fillet welding and butt welding with a small number of passes in single- or multi-wire systems.

Density approx. 1,1 kg/dm3

Basicity index 1,7
