DIN 8529          E  SY 55 76 Mn 1 NiMo B H5

AWS/ASME SFA-5.5                    E 9018-G-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.
