Select 409Cb

Stainless Steel / Metal Cored / Gas Shielded

Resources

Features

  • Increased level of columbium (Cb), also known as niobium (Nb), to prevent sensitization.
  • Enhanced weldability on components with excessive surface contaminants/lubes.
  • Metal cored construction inherently provides better welding performance compared to solid wires.
  • Designed to weld exhaust system components of similar composition, ~12 wt% chromium (Cr).
