FCW 317 LT Gas Shielded Flux Cored Welding Wire
Filler Metal FCW 317 LT is recommended for welding type 317 and 317L stainless steel to give a maximum of 0.04% Carbon in the weld deposit. The higher molybdenum content, as compared to type 316L, further reduces susceptibility to pitting corrosion.This flux cored wire is used in the pulp and paper industry and in other severe corrosion applications involving sulfuric and sulfurous acids and their salts.
FCW 317 LT was developed for flat or horizontal welding position (AWS E347T0-1/To-4).
This cored wire was formulated for use with 75% Argon/25% CO2 shielding gas; however, straight CO2 may also be used.
The 75/25 mixture will produce a smooth arc with virtually no spatter and slightly higher yield and tensile strengths than CO2.
The slag is self-peeling and minimizes cleanup.
The mechanical properties and deposit analysis will meet AWS 5.22 specifications with either gas.
