Will passivation effect the thermal emissivity of a polished SST surface?

Not at all.

Passivated metal will have a metal oxide layer on it, which in the case of iron will have a lower thermal permissivity.

The limitations on heat transfer will depend on the thickness of the film, which is oftentimes small enough to be negligible.
