Select 80C-D2

Low Alloy / Metal Cored / Gas Shielded

Resources

Features

  • Intended for welding of certain high strength, low alloy steels where a minimum tensile strength of 90 ksi is required in the deposited metal.
  • Can be used to substitute ER80S-D2 or ER90S-D2 solid wire.
  • Ideal for applications requiring weld metal which matches the mechanical properties of HSLA pressure vessel steels such as ASTM A302 Grade B, HSLA steels, and manganese-molybdenum castings such as ASTM A49, A291, and A735.
  • Offers many advantages over solid wires including less sensitivity to subsurface porosity, elimination of lack of fusion or “cold lap”, and 30-50% faster travels speeds for a given weldment size.
  • The recommended shielding gas is 75%Ar/balance CO₂, as higher argon blends increase the strength of the weld deposit.
