EN 499                   E 46 62 Ni B 42 H5

DIN 8529             E SY 42 87 2 Ni B H5

AWS/ASME SFA-5.5       E 8018-C1-H4

 

Application / Properties: Electrode for producing crack-free and tough welded joints. Weld metal is extremely metallurgical purity having a very low hydrogen content. Owing to its double covering (up to 3.25 mm SǾ), the electrode gas a stable and concentrated arc, thus being well suited or positional welding. Welds are of X-ray quality.
