Compare Corrosion of 304L to 316Lss with SO2

[Ace12]

I recently had some pipe installed for an SO2 line but I made the mistake of having fittings for two different projects sitting next to each other. So when the contractor finished their work I noticed that they had mixed in a few 304Lss fittings with the rest of the project that was 316Lss.

My question is does SO2 corrode 304Lss more than 316Lss?
