OK 61.80 is an acid rutile Nb stabilised, LMA and low carbon electrode for welding Nb or Ti stabilised steels of the 19Cr10Ni type. It has very good resistance against intergranular corrosion. The ferrite content level is rather high to ensure quite a good hot cracking resistance. The ferrite may transform to brittle phases at elevated temperatures. To avoid excessive embrittlent of the welds the maximum working temperature is limited to 400°C.
