AWS A5.22 E317LT0-1/-4 or E317LT1-1/-4
E347T1-1 is a flux-cored wire for single or multi-pass welds on AISI types 304, 304L, 321 and 347 stainless steels. E347T1-1 is noted for its low spatter generation, excellent bead shape and appearance and ease of slag removal. It has very good deposit efficiency when used for flat and fillet welds of medium and heavy thickness plates. It has been designed to be used with 100% CO2 shield gas. The columbium content of E347T1-1 provides weld deposits with improved resistance to chromium carbide precipitation and improved corrosion resistance as well as improved strength at higher temperatures. E347T1-1 is used extensively in the fabrication of AISI types 321 and 347 stainless steelstructures, pressure vessels, tanks in dairy, pulp and paper, textile dyeing, refinery and chemical equipment. The extra low carbon content reduces carbide precipitation.
E347T1-1 can be used to weld stainless steels of similar compositions when welds arerequired to meet higher corrosion resistance and higher creep strength requirements along with intergranular corrosion resistance requirements.
