CLASSIFICATIONS: E308LTO-1, E308LTO-4 per AWS A5.22
(Also meets E308TO-1, E308TO-4 per AWS A5.22)

APPROVALS: CWB E308LTO-1/4 (CO2/C25)

This 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%. SelectAlloy 308L's low carbon minimizes carbide precipitation and makes it more resistant to intergranular corrosion.

APPLICATIONS: SelectAlloy 308L 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 500F.
