AWS A5.22 E2553T
E2553T
E2553T is a flux cored, all position electrode with a nominal composition of 25% chromium, 9.5% nickel, 3.5% molybdenum, 2% copper and 0.2% nitrogen,E2553T is used to weld duplex stainless steels which contain approximately 25% chromium. It offers greater resistance to intergranular corrosion, pitting and stress corrosion cracking than 2209. Superb all position performance. Smooth, stable arc with very low spatter. Bead is shiny, smooth and silvery in appearance. Slag removes easily.
Applications
E2553T weld metal exhibits high strength with excellent corrosion resistance, especially to pitting attack from chlorides in sea water. E2553T is well suited for welding similar materials in the chemical and fertilizer industries, offshore pipelines, sour gas lines, etc.
