Epoxy Grout rusting?? - Page 2 - Contractor Talk - Professional Construction and Remodeling Forum

Stainless steel is an alloy. There are many grades. The 400 series does rust. Stainless relies on an oxide surface which it forms from exposure to oxygen for protection. Sand it and you remove the protection but it will reform IF it is exposed to air.

Sand it and you remove the protection but the steel will reform the protective layer IF it is exposed to air. By tiling over I think you may have prevented the layer from re forming.
I would re grout and seal the grout or use a silicone sealant.
