Welding Wire ER70S-6

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,Website:http://www.cztower.com, 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.Chemical Compositions of Welding Wire： CMnSiPSCrNiCuMoTiExample Value0.081.340.140.0150.0130.0210.0110.140.380.06Range≤ 0.101.20~1.60≤ 0.25≤ 0.030≤ 0.030≤ 0.20≤ 0.30≤ 0.200.30~0.50≤ 0.15Note: When the surface of welding wires is copper-plated, the copper content should not be more than 0.35%Fused Metal Mechanical Property(HJ350+14MnTiVRe) Tensile Strength Rm（ MPa）Yield Strength Rel(MPa)Elongation Rate A（ %）Ballistic Work Room Temperature -40℃ AKV(J)Example Value61849525101Range550~700≥ 470≥ 20≥ 27
