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



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


Description ofER70S-4 Mild Steel Welding Wire:
This mild steel copper coated welding wire ER70S-4 is with high anti-corrosionability and excellent welding properties, and it is suitable for CO2 gas Shieldedwelding. Based on the combined deoxidation of Si/Mn, it has better toughness.

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