AWS A5.22 E308LT

E308LT

E308LT is a gas-shielded, flux cored, stainless steel electrode has a nominal weld metal composition of 20% chromium, 10% nickel and a maximum carbon content of 0.04%. E308LT’s low carbon minimizes carbide precipitation and makes it more resistant to intergranular corrosion. Produces finely rippled, even and well washed bead. Smooth arc transfer with minimal spatter. Freely peeling slag minimizes cleanup time.

Applications

E308LT finds use in welded components for the chemical, paper, pharmaceutical and textile industries. It may be used to weld 301, 302, 304L, 308, and 308L stainless steel. Types 321 and 347 may also be welded as long as the service temperature does not exceed 500ºF.
