Application\/properties :<\/strong>
Basic electrode used for welding fine-grained structural steels with high strength. Weld metal is extremely metallurgical pure having very low hydrogen content. The electrode has a stable and concentrated arc, thus being well-suited or positional welding. Welds are of X-ray quality.<\/p>\n\n\n\n
