ER50-4, A18, ER70S-4, YGW12 Mild Steel Welding Wire

Description of ER70S-4 Mild Steel Welding Wire:
This mild steel copper coated welding wire ER70S-4 is with high anti-corrosion ability and excellent welding properties, and it is suitable for CO2 gas Shielded welding. Based on the combined deoxidation of Si/Mn, it has better toughness.

Application of ER50-4, A18, ER70S-4, YGW12 Mild Steel Welding Wire:
It is commonly suitable for welding high tensile steel at 490N/mm2 grade, at low current, and usually used for steel No.15 and 20.

Standard-compliant:
