Select ER439Ti

Stainless Steel / Solid / Gas Shielded


Features

  • Bare stainless steel electrode designed to weld exhaust system components of similar composition, ~18 wt% chromium (Cr), with increased oxidation resistance at high operating temperatures.
  • Nominally ~18 wt% Cr with titanium (Ti) as the stabilizing element to prevent weld metal sensitization.
  • 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.
