OK Flux 10.99
OK Flux 10.99 is an agglomerated basic flux designed for the submerged arc welding process of austenitic and ferritic-austenitic stainless steels, either using AC or DC current. Welding in AC usually provides good mechanical properties and better impact properties (when compared to DC current). This flux can be also used in DC to weld Ni-based alloys with Ni-based wires. 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.
