      MK·ER55-G

      Published:2009/12/17


      Standard:GB ER55-G   AWS ER80S-G
      Characteristics:MK 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.
      Application:With Ar-rich mixed gas shielded, it is widely applied to the welding of steel plate with strength grade of 550MPa, especially suitable to the welding of the railway locomotives and containers.
