AWS A5.22 E317LT0-1/-4 or E317LT1-1/-4
E317LT1-1 is a flux-cored wire for single or multi-pass welds on stainless steels. E317LT1-1 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.
E317LT-1 provides weld deposits with optimum ferrite content as its austenitic structure resulting in low susceptibilityto cracking. The extra low carbon content of E317LT-1 provides excellent resistance to inter-granular corrosion and stress corrosion cracking caused by carbide precipitation. E317LT-1 also provides excellent resistance to pitting corrosion due to its higher Molybdenum content compared to 316LT-1.
It’s used extensively in the fabrication of AISI type 317 stainless steel structures, pressure vessels, and tanks in dairy, pulp and paper, textile dyeing, refinery and chemical equipment. The extra low carbon content reduces carbide precipitation. E317LT-1 can be used to weld stainless steels of similar compositions when welds are required to meet higher resistance requirements. One key advantage of E317LT-1 is its excellent resistance to pitting corrosion in chlorine environments. It is also used for pollution control equipment where the corrosive attack is toosevere forE316LT-1 filler metal. E317LT0-1/-4may be more fluid giving a flat to concave bead profile.
