Is stainless and brass fittings okay to be used together on boiler systems?

I am just wondering if it is okay to use stainless steel fittings on a domestic hot water system.

I go through a lot of pipe flanges and nipples and I was pricing things out and most times the stainless pipe fittings are way cheaper than the bronze.

From the internet it looks like stainless is okay to be used on Domestic hot water systems but I couldn't find any info if it is okay to mix. I want to start using stainless nipples with brass relief valves, has anyone had any issues? is their any sort of reaction when mixed?

thanks for any help.
