    Do non-metallic inclusions promote corrosion in a stainless steel? The corrosion could be introduced via Microbial Induced Corrosion (MIC) or other.[/list]

    The inclusion could create a stress riser, and stress is a factor in stress corrosion cracking of stainless steel. So I think the answer is probably yes.

    Keep in mind that "stainless" is a relative term. Not absolute. Some chemicals will rreact to it. A few jobs back, we used to have the stainless steel we used "passivized" that came in contact with the chemicals. One such chemical was SodiumFerroCynide. I've seen stainless steel get some funny stains when it wasn't passivized. A better corrosive resistant metallic material yet is Hastalloy.
