AWS A5.22 E2209T
E2209T
E2209T 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. Bead is shiny, smooth and silvery. Provides a stable, smooth arc with very low spatter. Superb performance in all positions.
Applications
E2209T 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.
