Send Message Request a Quote

The ER70S-6 gas shielded arc welding wire is designed for high-strength low-alloy steel (e.g. Q390, Q420 and Q460) with copper addition. This H08MnMoA welding wire incorporates with related flux to offer outstanding wedability, stable arc, and high slag detachability.

Our gas shielded arc welding wire generates flawless bead, offering prominent crack resistance and impact toughness at low temperature. This HSLA welding consumable is highly recommended for automobile, hoisting machinery, transport machinery, engineering machinery, shipbuilding, power plant, petrochemical engineering, bridge and pressure vessel, etc.
