316L vs 316LSI?

[SquareOneBeads]

I called the local welding shop and asked if they had 316L TIG rods. They only have 316LSI which means they have more silicone than a 316L. Does anyone know if this matters? I asked about 308 and they also have only the LSI not the L.

If anyone has any info on this I would appreciate it.

Thanks,
Heather
