Abstract
Multistage process for the pickling of a stainless steel having martensitic structure, characterized in that in a first stage the steel is treated with an aqueous solution containing hydrofluoric acid and hydrochloric acid, and that in a second stage the steel is treated with a second aqueous solution containing hydrogen peroxide and hydrofluoric acid.
