Description:
Maxeta 21 is a zircon-basic low hydrogen iron powder electrode with 170% recovery, intended for
welding heavier sections in construction and ship steels. It is designed for fast and easy welding in
the horizontal position and operates well on both AC and DC. Maxeta 21 can be used on
primer-treated material without porosity or other problems and gives good mechanical properties.
