I have electropolished stainless steels, mainly 304 & 316. I have tried electropolishing 400 series stainless steels, but they do not develop the highly bright finish that 304 & 316 achieve when electropolished using solutions containing phosphoric and sulfuric acid. I believe the Electropolishing Engineering Handbook lists some formulas for 400 stainless steel elcectropolishing. Also some of the suppliers in this forum I believe market 400 series stainless steel electropolishing processes.
