Print Sheet 


CLASSIFICATION: E309T0-3 per AWS A5.22

This lower cost, self-shielded, flux cored, stainless steel wire has a nominal weld metal composition of 24% chromium and 13% nickel with a maximum carbon content of 0.10%.

APPLICATIONS: SelectAlloy 309T0-3 is used for the cladding of carbon steels, for the welding of Type 309 stainless steel and for the joining of carbon and low alloy steels to austenitic stainless steels where lower carbon levels are not required.

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

SHIELDING GASES: Self-shielded

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Produces a flat, well washed bead.
  • Delivers an arc transfer that is globular with low spatter.
  • Offers lower penetration than with gas-shielded wires, making it ideal for surfacing or welding over gaps.

* 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.
