OK Flux 10.99
OK Flux 10.99 is a neutral agglomerated basic flux designed for the submerged arc welding process of austenitic stainless steels with relevant wires, either using AC or DC+ current. This flux can also be used in both current modes to weld Ni-based alloys with carefully chosen Ni-based wires. Welding in AC usually provides good mechanical properties and better impact properties (when compared to DC+ current). The high basicity of OK Flux 10.99 gives better impact values, regardless of the current being used. It also has very good weldability in 1G and 2G position; the slag is self-lifting or easily detached leaving clean and nice bead appearance.
