ER55-G 0.8/1.0/1.2/1.6mm Weathering Steel Solid Welding Wire
ER55-G is copper coated gas shielded welding wire for low alloy high strength steel with strength grade of 550-600 MPa. Due to the enough quantity of element Mn,Si,Cu,Cr,Ni etc in this welding wire, the weld has good atmospheric corrosion resistance.
Conform to Standard :TB/T 2374 ER55-G
GB ER55-1
Specification:It comes with Argon - rich gases protection. The deposited metal has good atmospheric corrosion resistance, crack resistance, good shaping and toughness.
Purpose:Suitable for welding 550MPa high strength weathering steel,such as construction machinery, bridges, etc.
