Introduction:
ER70S-6 is a copper-plated low alloy steel wire and has excellent weldability.It has low spatters while welding and can be performed at all positions. It has beautiful weld appearance. Owing to the strong binding strength of the copper layer, it has a strong rust-resisting property,so it can be fed smoothly and stably.Higher impact toughness can be obtained from its weld at low temperature.
Application:Used for welding all kinds of 500MPa structural steel parts and for welding all kinds of 500MPa plates and pipes. such as vehicles , vessels, bridges, building machines and containers etc.
Packing: 1kg/5kg/10kg/15kg/20kg/spool in carton, 250kg/ drum, 21.6MT -25.2MT per 1X20" FCL.
