Properties And Applications

Heavy coated basic type electrode with high efficiency, for welding low alloy high strength steels, fine grained structural steels and high strength steel pipes. Provides high crack resistance under difficult conditions such as dynamic loads, impact, pressure, vibration and service temperatures between -60°C and 450°C. Weld deposit is of a extremely high metallurgical purity and very low hydrogen content. Especially 2,50 mm and 3,25 mm diameter electrodes feature stable and concentrated arc, rendering it well-suited fore positional welding. Suitable for welding and repair jobs up to X70 oil and gas pipes. Weld are of X-ray quality.
