EN ISO CODE:
D&H-3U is a specially designed electrode for welding U3 steel. The weld metal has excellent crack resistance and has good scaling resistance. It produce quiet and stable arc, which is easy to strike and re-strike. Detachability of slag is very easy. The weld metal is of radiographic quality. Ideal for joining ferritic to austenitic steels, armour plates, austenitic manganese steels, dissimilar materials, etc.
