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 with nanomaterials is resistant to moisture absorption for 9 hours in humid environments with 80% humidity.
This electrode used for welding fine-grained steels used in pressure vessels, boilers, pipes, steel structures, dam construction and shipbuilding. Its weld is tough and crack-resistant and has low hydrogen content. The electrode has a stable and concentrated arc, thus being well-suited or positional welding. Welds are of X-ray quality.
