OK Flux 10.71 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 solid wires and cored wires and thus it is suitable for all kinds of steels. OK Flux 10.71 combines good toughness values with excellent weldability. It is used for single and multiwire 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.
The good slag detachability and limited alloying of Si and Mn make it well-suited for multi-pass thick-section welding. High welding speeds can be achieved by producing a finely rippled weld metal, all this in combination with very good impact values. In general construction, OK Flux 10.71 is one of the most used SAW fluxes.
Not just for structural steels and fine-grained steels, but also 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 50mm requires not only excellent slag detachability, particularly in the first run, and high deposition rates in all following runs, but also excellent toughness values.
Since OK Flux 10.71 offers all this as it is well established in this market segment. Other applications are in shipbuilding with approvals or the production of pipes with steels up to X70 strength level. OK Flux 10.71 can also be combined with several SAW cored wires to increase the productivity and the mechanical properties of the weld metal.
