AWS A5.22 E347T
E347T
E347T has a nominal weld metal composition of 19.50% chromium, 10% nickel and 0.6% columbium. This gas-shielded, flux cored, stainless steel electrode’s columbium content forms a stable carbide, which reduces chromium carbide precipitation and makes the weld metal more resistant to intergranular corrosion. Produces a finely rippled, even and well washed bead. Freely peeling slag reduces cleanup time. Smooth arc transfer with minimal spatter.
Applications
E347T is used to weld Types 321, 347 and 348 stainless steel, SelectAlloy 347 welds furnace parts, pressure vessels, chemical tanks and automotive parts.
