Abstract: The chemical polishing of steel surfaces is carried out by bringing the latter into contact with a bath comprising, in aqueous solution, hydrochloric acid, phosphoric acid, nitric acid and ferricyanide complex ions. The invention is in particular applicable to the polishing of vessels of large dimensions made from stainless steel alloyed with chromium and with nickel.
