Select 81-Ni2

Low Alloy / Flux Cored / Gas Shielded

Resources

Features

  • Produces beads with good geometry, a smooth rippled surface, and easily removable, thin slag
  • Excellent low temperature Charpy impact results due to the 2.5% nickel addition.
  • Used to weld steels such as ASTM A203, A572, A575, A734, and steels containing 2% nickel.
  • Ideal for applications such as offshore platform construction, earthmoving and minery machinery, and shipbuilding.
