Abstract: Baths for chemical polishing of stainless steel surfaces, comprising, in aqueous solution, a mixture of hydrochloric acid, phosphoric acid and nitric acid, ferricyanide complex ions and an additive capable of decomposing nitrous acid. The baths can be used in particular for chemical polishing of heat exchangers with a very large exchange surface.

Abstract: Process for inhibiting the corrosion of a mass of metal (2) in contact with an acid bath (3) containing ferric ions, according to which at least a part of the bath (3) is circulated through a stack of felts (10) made of carbon or graphite, alternating with perforated plates made of iron or an iron alloy (9). The process applies to the pickling of metallurgical products made of steel in hydrochloric acid baths.
