WEATHERING STEEL-Cor-Ten®
Description
Basic coated electrode for weather resistant steels
Basic coated welding electrode producing a low alloyed deposit for welding weather resistant steels with excellent mechanical properties. Enriched with small percentages of Cr, Ni, Cu and P the weld metal do not require any type of painting or finishing to resist atmospheric corrosion phenomena. Mainly used for civil infrastructures as for bridges, pylons, security components and structural constructions, et. Suitable for positional welds except vertical down, spatter free, stable arc, regular fusion and
easy deslagging.
