ER 309LSi 0.035 x 25 lb Spool AWS A5.9 309LSi

Excellent for Dissimilar Metal Welding
High Chromium & Nickel Content
Low Carbon (L Grade) – Improves resistance to intergranular corrosion
Higher Silicon Content – Better weld pool fluidity, smoother, cleaner weld bead, improved wetting and fusion, enhanced arc stability
Smooth Weld Appearance
Crack-Resistant
Suitable for Buffer Layers
Good Performance at Moderate Temperatures

SKU: 25309LSI035 Category: MIG Wires (GMAW) Brand: Inweld

Description

This classification is the sames as 309L, except for the higher silicon content. This improves the usability of the
filler metal in the gas metal arc welding process. If the dilution by the base metal produces a low ferrite or fully
austenitic weld, the crack sensitivity of the weld is somewhat higher than that of a lower silicon content weld
metal. This wire is designed for joining stainless steel to mild or low alloy steels.
