EN 499Application/properties :
Basic electrode used for welding high strength, low-alloyed steel. The electrode is designed for various applications, including pipelines. 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.
