Welding Wire ER70S-6

Product Details

ER70S-6 is a kind of low-alloy high-strength steel copper-plated submerged arc welding wire. It is widely applied to welding of low-alloy high-strength steel (for example, Q390, Q420 and Q460) in automobiles, hoisting machinery, transportation machinery, engineering machinery, ships, power stations, petrochemicals, bridges, pressure containers, etc.. Partial matched weld fluxes: sintered flux: SJ101, SJ107, SJ301 and SJ501; and fused fluxes: HJ250, HJ350, HJ431, etc.
