The E71T-5C gas shielded mild steel flux cored wire involves the utilization of TiO2-CaF2 slag system. Thus our welding wire is highly characterized by excellent weldability, smooth arc, fine spatter particle, easy slag removal and perfect bead. Based on outstanding mechanical properties, this product shows impressive impact toughness at -30℃.

This gas shielded mild steel flux cored wire comes with less than 5ml/100g diffusible hydrogen content. Our all position wire product is specialized for welding of low carbon steel and high strength low alloy steel with 500MPa tensile strength. Therefore, this filler material has been applicable for industries of marine engineering, pressure vessel and electric power.
