Description: AK-J507RH is an ultra-low hydrogen high toughness low alloy steel electrode with low hydrogen sodium type alkaline
coating. With DC reverse connection, all-position welding can be performed. The welding process performan-ce is excellent, the arc is
stable, the spatter is small, the slag removal is easy, and the welding seam is beautiful. The weld metal has good plasticity, low
temperature toughness and crack resistance.
Application: Suitable for welding of ships, bridges, offshore platforms and other important structures.
