Stainless steel can be anodized in baths containing sulphuric acid and  hexavalent  chromium compounds.<ref>Handbuch der Galvanotechnik Band III, eds. H. Dettner and J. Elze, Munich 1969., p.291</ref> Baths containing NaOH or KOH solutions can be  used too.As hexavalent chromium compounds are prohibited for use in the EU based on ROHS regulations and are toxic and carcinogenic, solutions based on molybdate are proposed as a replacement (e.g. molybdate 30-100g/ boric acid 10-18 g/manganese sulfate 0.5 - 5 g/1 liter of water, 0.1 - 20 A/dm2, 0.1–15 minutes).<ref>{{Cite web|url=https://patents.google.com/patent/CN103114320B/en|title=A kind of coloring liquid painted for stainless steel electrochemical and colorize method}}</ref><ref>{{Cite thesis|url=https://repository.lboro.ac.uk/articles/thesis/The_electrochemical_colouring_of_austenitic_stainless_steel_in_sodium_molybdate_and_other_environmentally_benign_solutions/12530660/1|title=The electrochemical colouring of austenitic stainless steel in sodium molybdate and other environmentally benign solutions|first=George|last=Alliott|date=July 9, 2020|publisher=Loughborough University |doi=10.26174/thesis.lboro.12530660.v1 |via=repository.lboro.ac.uk}}</ref>
