OK Flux 10.71L
OK Flux 10.71L is an agglomerated, basic flux for submerged arc welding. It is used for single and multi-run welding of all plate thicknesses. It can be combined with a wide range of wires and thus it is suitable for all kinds of steels. OK Flux 10.71L combines good toughness values with excellent weldability. It is used for single & multi-wire procedures such as tandem, twin-arc, tandem-twin welding and many more, for butt, overlap and fillet welds. It works equally well on DC and AC current. The good slag detachability and limited alloying of Si and Mn makes it well suited for multi-pass thick section welding.
In general construction, OK Flux 10.71L is one of the most used SAW fluxes. Not just for structural steels and fine-grained steels, but also for weather resistant steels e.g. for bridges. Pressure vessels are welded with this flux, because it can be used for a wide range of steels including low temperature steels. This reduces the number of different fluxes a customer needs to have in stock. Wind tower production with plate thicknesses of greater than 50 mm require not only excellent slag detachability particularly in the first run, high deposition rates in all following runs and also excellent toughness values. Since OK Flux 10.71L offers all this it is well established in this market segment. Other applications are in shipbuilding or in the production of pipes with steels up to X70 strength level.
