Description: AK-J556RH is an ultra-low hydrogen high toughness low alloy steel electrode with low hydrogen potassium
type alkaline coating. AC and DC dual-use, can perform all-position welding. The welding process performance is
excellent, the arc is stable, the spatter is small, the slag removal is easy, and the welding seam is beautiful. The
deposited metal has excellent plasticity, toughness and crack resistance.
Application: It is suitable for the welding of important low-alloy steel structures such as offshore oil production
platforms, ships, and pressure equipment.
