CLASSIFICATION: EC308LSi per AWS A5.22

APPROVALS: CWB EC308LSi

SelectAlloy 308LSi-C features a weld metal composition of 21% chromium, 10% nickel, .8% silicon and a maximum carbon content of .03%. This metal cored electrode’s higher silicon content level improves bead wetting and its low carbon content minimizes carbide precipitation, making it more resistant to intergranular corrosion.

APPLICATIONS: SelectAlloy 308LSi-C is designed for making small butt, lap and fillet welds on thin material at elevated travel speeds. This wire is utilized to weld 301, 302, 304L, 308 and 308L grades of stainless. Standard applications for SelectAlloy 308LSi-C include in-welded components for the chemical, paper, textile and pharmaceutical industries and food service equipment.
