CLASSIFICATIONS: E347T1-1, E347T1-4 per AWS A5.22

SelectAlloy 347-AP is a gas-shielded, flux cored, all position stainless steel electrode with a nominal weld metal composition of 19.5% chromium, 10% nickel and 0.5% columbium (niobium). The columbium forms a stable carbide which reduces chromium carbide precipitation and makes weld metal more resistant to intergranular corrosion.

APPLICATIONS: SelectAlloy 347-AP is utilized in the welding of furnace parts, pressure vessels, chemical tanks and automotive parts. It is also used to weld Types 321, 347 and 348 stainless steels.

DIAMETERS: .045", 1/16"

SHIELDING GASES: 100% CO2, 75-80% Ar/balance CO2, 40-55 cfh

WELDING POSITIONS: All positions

CHARACTERISTICS:

  • Flat, well washed beads achieved with minimal weaving.
  • Excellent slag peeling minimizes cleanup.
  • Very low spatter.
  • Outstanding all position performance.
