Application and User
Westward 20AN41 is a MIG welding wire designed for joining stainless steel grades 304L, 304LN and 308L using the GMAW process. It suits fabricators and maintenance shops that require consistent wire feed from a 30 lb plastic spool.
Standard Limits
The wire meets AWS A5.9 classification ER308LSi with a diameter of .030 in and operates on DCEP current. As-welded tensile strength reaches 85 ksi while minimum yield strength is rated at 55 ksi, defining the mechanical envelope for qualified procedures.
Build and Handling
Stainless steel construction on a plastic spool resists corrosion during storage and feeds smoothly through standard MIG guns. The 30 lb package supports extended production runs without frequent changeovers, though operators must observe Proposition 65 warnings for chemical exposure.

Questions about this item
Should I pick the 0.030 in ER308LSi on a 30 lb spool or a smaller diameter for my MIG setup?
The 0.030 in diameter suits general-purpose stainless MIG work on 304L and 308L grades; thinner wire feeds easier on lower-amp machines while thicker wire deposits faster on heavier plate.
What does the 85 ksi tensile strength mean when I am welding 304L stainless?
An 85 ksi as-welded tensile strength indicates the deposited metal will match or exceed the base metal strength on 304L, 304LN and 308L grades when run DCEP with proper shielding gas.
How does the AWS A5.9 ER308LSi classification limit what I can weld?
AWS A5.9 ER308LSi certifies the wire for stainless-to-stainless MIG welding on 304L, 304LN and 308L using DCEP polarity; it is not rated for dissimilar metals or other processes.
