Epoxy Grout Rusting??

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.

I would re grout and seal the grout or use a silicone sealant.
