E317LT

E317LT is a gas-shielded, flux cored, stainless steel electrode offers a nominal weld metal composition of 19.5% chromium, 13% nickel, 3.5% molybdenum and a maximum carbon content of 0.04%. The higher level of molybdenum in SelectAlloy 317L improves resistance to pitting and provides increased creep resistance. Its low carbon content minimizes carbide precipitation and makes it more resistant to intergrannular corrosion. Provides improved pitting resistance. Increases creep resistance. Produces a smooth arc transfer with minimum spatter. Easy peeling slag reduces cleanup time.

Applications

E317LT delivers improved pitting resistance compared to 316L and is an excellent choice for applications involving solutions of sulfuric acid and sulfur bearing gases. Utilized to weld Types 316 and 317 stainless, SelectAlloy 317L finds wide application in the pulp and paper industry as well as in food and pharmaceutical processing equipment.
