CLASSIFICATION: EC439 per AWS/ANSI A5.22, ASME SFA 5.22

Select 439Ti is a composite metal cored, stainless steel electrode for gas-shielded arc welding. This product is designed for welding ferritic stainless thin stock or sheet steel in the fabrication of automotive exhaust system components. The 439 alloys are higher in chromium than the 409 series in order to provide better heat and corrosion resistance. This particular grade is titanium stabilized.

APPLICATIONS: Select 439Ti is a titanium stabilized, 18% chromium stainless steel electrode intended to weld sheet metal and thin stock of similar composition. This material is primarily used in the fabrication of automotive exhaust systems subjected to higher temperatures and corrosion than the 409 series. Typical components to be welded are manifolds, mufflers,
catalytic converters and exhaust tubing.

DIAMETERS: .045", .052", 1/16"

SHIELDING GAS: 98% Ar/2% O2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Handles poor fit up and gaps better than solid wire.
  • Smooth arc with low spatter.
  • Exceptionally good bead contour.
  • Better heat and corrosion resistance than 409 types.
