E308LT-3
AWS A5.22 E308LT0-3 | ASME SFA 5.22 E308LT0-3 (T0 = flat and horizontal)
E308LT-3 is a flux cored self shielded wire for single or multi-pass welds on stainless steels which 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 . E308LT-3 provides weld deposits with optimum ferrite content in its austenitic structure resulting in low susceptibility to cracking. The extra low carbon content of E308LT-3 provides excellent resistance to intergranular corrosion and stress corrosion cracking. E308LT-3 is used extensively in the fabrication of stainless steel structures, pressure vessels, tanks used in dairy, pulp and paper, textile dyeing, refinery and chemical equipment. The extra low carbon content reduces carbide precipitation. E308LT-3can be used to weld stainless steels of similar alloy composition including AISI 304L, 308L, 321, 347, and CF-3, CF-8 or whenever welds are required to meet structural and intergranular corrosion resistance requirements.
low carbon content of E 308LT1 provides excellent resistance to intergranular corrosion and stress corrosion cracking.
