Acid rutile covered MMA-electrode for welding Nb-or Ti stabilized steels of the CrNiMo 18-12-3 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.
