SelectAlloy 2216HT-C

Nickel Alloy / Metal Cored / Gas Shielded


Features

  • Designed to weld high strength grades of nodular cast iron components and for the welding of dissimilar joints between silicon-molybdenum alloyed cast irons and 400 series stainless steel.
  • Nominally ~12 wt% manganese (Mn) addition in a nickel-iron system improves the flow of the molten metal and increased the crack resistance of the weld metal.
  • Additions of ~7 wt% chromium (Cr) and ~0.7 wt% columbium (Cb), also known as niobium (Nb), promote a more stable microstructure with enhanced resistance of HAZ cracking to increase service life durability.
  • Applications for this alloy type include cast iron intake manifolds to dissimilar steels found in automotive exhaust systems or general repair welding of cast iron parts.
  • Designed to weld high strength grades of nodular cast iron components and for the welding of dissimilar joints between silicon-molybdenum alloyed cast irons and 400 series stainless steel.
  • No AWS class, Modified ERNiFeMn-CI chemistry per AWS A5.15, ASME SFA 5.15
