 Print Sheet


CLASSIFICATIONS: E347T0-1, E347T0-4 per AWS A5.22

SelectAlloy 347 has a nominal weld metal composition of 19.50% chromium, 10% nickel and 0.6% columbium. This gas-shielded, flux cored, stainless steel electrode’s columbium content forms a stable carbide, which reduces chromium carbide precipitation and makes the weld metal more resistant to intergranular corrosion.

APPLICATIONS: Used to weld Types 321, 347 and 348 stainless steel, SelectAlloy 347 welds furnace parts, pressure vessels, chemical tanks and automotive parts.

DIAMETERS: .045", 1/16"

SHIELDING GASES: 100% CO2, 75-80% Ar/balance CO2, 40-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Produces a finely rippled, even and well washed bead.
  • Freely peeling slag reduces cleanup time.
  • Smooth arc transfer with minimal spatter.
