Print Sheet 


CLASSIFICATION: E347T0-3 per AWS A5.22

A self-shielded, flux cored, stainless steel electrode, SelectAlloy 347T0-3 has a nominal weld metal composition of 20% chromium, 10% nickel and 0.7% columbium. The columbium forms a stable carbide which reduces chromium carbide precipitation and makes the weld metal more resistant to intergranular corrosion.

APPLICATIONS: SelectAlloy 347T0-3 is designed to weld Types 321, 347 and 348 stainless steels. It may also be used for the cladding of carbon steels.

DIAMETERS: .045", 1/16", 3/32"

SHIELDING GASES: Self-shielded

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Excellent for surfacing or welding over gaps.
  • Produces a flat, well washed bead.
  • Delivers a globular arc transfer with low spatter.

* The nitrogen levels in self-shielded stainless steel deposits can vary widely depending on the welding parameters used. Since nitrogen has a strong effect on the ferrite level (increasing nitrogen lowers the ferrite number), careful control of parameters is necessary to maintain consistent ferrite levels.
