ER70S-4
AWS A5.18 ER70S-4
Description：
ER70S-4 is a premium wire for welding on all grades of mild and carbon steels, producing quality welds with minimal porosity. It is a triple deoxidized wire (Zirconium, Titanium, and Aluminum) making it an excellent choice for welding over rust and mill scale. Used for carbon steels and alloy steels with 500MPa tensile strength structures welding, and high speed welding of sheet plates and pipelines
