Westward 20AN71 ER309LSi 2 lb Spool
Westward 20AN71 is a 2 lb spool of MIG welding wire classified ER309LSi. The 0.030 in diameter stainless steel wire is designed for GMAW processes. It suits fabricators joining stainless to carbon or low-alloy steels.
Suits dissimilar stainless joints.
This wire suits shops welding 304, 304N, 305, 308, 309 or 309S grades to carbon or low-alloy steel. Buyers who need wire for aluminium, mild steel only, or other stainless grades should look at a different classification.
0.030 in ER309LSi wire diameter
The single specification that decides fit is the 0.030 in ER309LSi wire diameter. Match this size and classification to the welder setup and the base metals listed to ensure correct deposition and mechanical properties.

Questions about this item
What MIG welder specifications do I need to run this 0.030in ER309LSi wire?
Your MIG welder must accept 0.030in solid wire on a 2 lb plastic spool and be set for GMAW process with appropriate drive rolls and liner for stainless wire.
Can I use this ER309LSi wire to join 304 stainless parts to my existing carbon steel workpieces?
Yes, this wire is formulated for stainless steel to carbon steel, low-alloy steel, and stainless steel joints, covering grades 304, 304N, 305, 308, 309, and 309S.
How can I verify the welds meet the 87 ksi tensile and 64 ksi yield strengths after welding?
Check for smooth bead appearance, minimal spatter, and proper fusion; confirm mechanical properties by sending representative test coupons to a lab for tensile and yield testing per AWS A5.9.
