OP 41TT

OP 41TT is an agglomerated fluoride-basic type flux for welding high-tensile fine-grain structural steels as well as heat-resistant structural steels. In the nuclear sector it is used for many applications in combination with different wire electrodes, such as reactor pressure vessels, steam generators, pressurizers, reactor safety tanks and pipes in the primary and secondary circuits as well as the auxiliary units. OP 41TT is used with wire electrodes containing a higher level of manganese and silicon, such as e.g. OE-SD3. OP 41TT can be used on DC+, AC or multi wire tandem configurations
