SG3 Copper coated double-deoxidised mild steel MIG wire, with increased silicon and manganese content, for welding unalloyed and low-alloyed mild and medium tensile steels requiring good impact toughness down to -20°C. Manufactured with a high-quality copper finish for improved feeding.Precision layer wound. SG3 typically provides a higher ultimate tensile strength over standard SG2.
Suitable for use in general fabrication, construction, ship building, tanks and boilers, repair and autobody applications. Comprises increased manganese and silicon to provide improved mechanical properties. Can be used on a wide variety of mild steels, structural steel, fine-grain steel, pipe steel, boiler steel and cast steel. Popular in the construction, power generation and offshore sectors.
