CHW-50C6 accord: GB E50-6 considerable: AWS ER70S-6 CHW-50C6 BS A18 JIS YGW16 Description: CHW-50C6 is copper low alloy steels with good welding performance, weld appearance, spatter, can be all-position welding. Copper wire layer adhesion and anti-corrosion and strong, stable welding wire, welding with high and low temperature impact resistance. Uses: Used for welding low carbon vehicles, ships, bridges, construction machinery, container, etc., and low-alloy steel structure.
