OP 76

OP 76 is an agglomerated, fluoride-basic type flux for welding stainless and heat-resistant steels. The flux is also suitable for welding Duplex and fully austenitic steels and nickel alloys. In terms of weld metal carbon content, the behaviour of OP 76 can be described as neutral, so that low carbon steels can be welded if suitable wires are used. In terms of silicon and manganese, the metallurgical behaviour is neutral. The flux is highly basic and therefore features a high resistance to hot-cracking. Thus it is particularly well suited for joint welding large cross-sections. Good slag detachability when used with titanium and niobium free wire electrodes.
