CLASSIFICATION: E309LT0-3 per AWS A5.22
(Also meets E309T0-3 per AWS A5.22)

This self-shielded, flux cored, stainless steel electrode has a nominal weld metal composition of 24% chromium and 13% nickel with a maximum carbon content of 0.03%. The low carbon maximizes carbide precipitation and makes the weld metal more resistant to intergranular corrosion.

APPLICATIONS: SelectAlloy 309LT0-3 is utilized for the cladding of carbon steels. It may also be used to weld Type 309 stainless steel and to join carbon and low alloy steels to austenitic stainless steels.

DIAMETERS: .035", .045", 1/16", 3/32"

SHIELDING GASES: Self-shielded

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Produces an arc transfer that is globular, with low spatter.
  • Well suited for surfacing or welding over gaps.
  • Provides a flat, well washed bead.

* 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.
