ESAB OK Flux 10.72 - Bonded - 55 lb Bag - 1072000P0A

OK Flux 10.72 is a neutral, bonded aluminate-basic flux. It is primarily used for for applications with toughness requirements down to -50°C in high dilution joints. It provides excellent slag removal also in narrow V-joints. It is recommended for joining structural steels, fine grained steels and creep resistant steels. It has proved to be especially appropriate for wind tower productions. OK Flux 10.72 features extremely high current carrying capacity and is intended for single or multi wire procedures using DC and AC power. It can be used for single layer and multi layer welding of unlimited plate thickness.
