Select ER18CrCb

Stainless Steel / Solid / Gas Shielded


Features

  • Nominally ~18 wt% Cr with columbium (Cb), also known as niobium (Nb), as the stabilizing element to prevent weld metal sensitization.
  • Nb stabilization promotes enhanced weldability on components where cleanliness can be an issue (i.e. excessive debris, oil, etc.).
  • Unique manufacturing techniques provide enhanced arc stability and stable feeding.
  • Applications for this alloy type include ferritic stainless steel exhaust system components, converters, mufflers, and tubing of similar composition where heat and corrosion resistance are necessary.
