OK 61.85

OK 61.85

OK 61.85 is a basic Nb-stabilized electrode designed for welding of Nb- or Ti-stabilized stainless steels of the 19Cr10Ni-type. It has very good resistance against intergranular corrosion. OK 61.85 provides the best hot cracking resistance of the E347 type electrodes due to the combination of the high ferrite content level and the basic coating. Ferrite may transform to brittle phases at elevated temperatures. To avoid excessive embrittlement of the welds the maximum working temperature is limited to 400°C.
