OK Flux 10.16 is an agglomerated, fluoride basic, non-alloying flux for submerged arc welding specially designed for butt welding and overlay welding with nickel-based alloyed wire. Can also be used for overlay welding with nickelbased strips. It is primarily used for multi-run welding of thick section materials.OK Flux 10.16 is suitable for single layer and multi-layer welding of unlimited plate thickness and for strip cladding. It can only be used on DC current when butt welding with nickel-based alloy wires. This flux has good weldability in the 2G/PC position and the well balanced flux composition minimises silicon transfer from the flux to the weld metal providing good mechanical properties, particularly good impact toughness reducing the risk of hot cracking. It is also suitable for submerged arc strip cladding with all grades of nickel-based strips.Applications include components of chemical and petrochemical plants, offshore constructions and pressure vessels.
