Application\/properties:<\/strong><\/p>\n\n\n\n

Basic electrode used for welding fine-grained steels used in pressure vessels, boilers, pipes, steel structures, dam construction and shipbuilding. Its weld is tough and crack-resistant and has 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
