CLASSIFICATIONS: E2209T1-1, E2209T1-4 per AWS A5.22, ASME SFA 5.22

SelectAlloy 2209-AP is a flux cored electrode designed to weld duplex stainless steels of the 22Cr-9Ni-2Mo-N type. The weld deposit has a "duplex" microstructure of austenite and ferrite and normally gives ferrite in the range of 25-40 FN. Argon with 20-25% CO2 is the recommended shielding gas.

APPLICATIONS: The all position SelectAlloy 2209-AP is designed to weld similar materials in the chemical and fertilizer industry, off-shore pipelines, sour gas lines, etc… It is used to weld 2205, 2304 and other similar types of duplex stainless steel.

DIAMETERS: .045", 1/16"

SHIELDING GASES: 75-80% Ar/20-25% CO2, 40-55 cfh

WELDING POSITIONS: All positions

CHARACTERISTICS:

  • Bead is shiny, smooth and silvery.
  • Provides a stable, smooth arc with very low spatter.
