Properties and Applications

Heavy coated basic type electrode for welding fine grained structural steels and especially cryogenic steels. Electrode produces tough and crack-free welded joints. Weld deposit is of extremely high metallurgical purity and very low hydrogen content. Owing to high crack resistance under difficult conditions such as dynamic loads and low service temperatures up to -60°C. It is suitable for use in welding of storage tanks and piping which are subjected to low temperatures. Electrode features a stable and concentrated arc. Especially 2,50 mm and 3,25 mm diameters are well-suited for positional welding. Welds are of X-ray quality.
