AWS/ASME SFA-5.5:E 55 4 Mn1NiMo B T 42 H5
EN 18275-AApplication/properties :
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.
