ER309LSI is similar in composition to ER309L with a higher silicon content, which produces weld beads that are exceptionally smooth due to good wetting action.
Works great for TIG when small diameter TIG wire is not always available locally, and is never cheap if it is!
Like others, I purchased this to use as TIG wire since I couldn’t get any tig wire local in 309/.045″, and this roll was only $7. Works wonderfully once you take the coil out of each piece of filler rod by hand shaping or chucking up one end of filler wire in your drill and the other end of filler in a vise (then using the drill motor to twist the filler rod straight….or straight-ish. Stainless doesn’t straighten out quite as nice as ER70S-2/ER70S-6 with a drill motor).

Original 2 star rating: The part description is 309LSI x .023. Received 308LT1 x .045 wire. Sending it back for a replacement. See photo for how it is mis-lableld.
Sweet deal for 309 filler. Goes a long way on TIG and works well.
This wire works really well for TIG. I needed small filler for detailed work and random jobs that I get. This stuff flows pretty well and pulls crap out of the puddle probably better than er70 for unknown steel composition repairs. I’ve flowed some of this into cast iron and the great elongation allowed by 309 seems to be really well matched for that job. (I tack with a high elongation alloy though)
