Galvanic corrosion "galling" between active 410, 304, & 316 Stainless and Cast Iron or Cast Steel is not slowed enough by the application of Nickel based anti-sieize compounds to be equal to steel bolts with the same coating. Be careful of your anti-seize flavor of choice. Copper based anti-sieze can cause galling in aluminum and stainless parts.
Passivated 304 & 316 stainless, either by oxidizing in an air furnace or treating the surface with an acid to cause an oxide to form, is much better at resisting galling but is also more expensive.
