Debbbbbbion A general-purpose, hardfacing electrode depositing a corrosion-resistant fully martensitic steel. The electrode is suitable for hardfacing shafts, racks and pinions, bbbbs and pins, valve seats of cast steel, mixer arms, feed gear, knives, loading buckets and track rollers. Generally, a preheat and interpass temperature of about 200°C is recommended for most applications. Welding current AC, DC+ OCV 70 V 12346
