AWS/ASME SFA – 5.5 :E Y 5076 Mn 1 Ni B H5
DIN 8529 :E 50 6 Mn 1 Ni B 42 H5
EN 499 :Application/properties:
Basic electrode that uses nano technology in a humid environment with 80% humidity, the electrode coating is resistant to moisture absorption for 9 hours. This electrode is suitable for producing crack-free and tough welded joints. 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.
