Abstract
A procedure for chemical etching and dissolution of stainless steel surfaces in a pickling solution, characterized in that the stainless steel surface is subjected to an etching reaction with a stabilized pickling solution, containing: (a) hydrogen peroxide, (b) an inorganic acid containing halogen ion selected from the group consisting of hydrochloric acid, hydrofluoric acid, hydrobromic acid and hydroiodic acid and its salts, (c) an inorganic acid selected from the group consisting of sulfuric acid and phosphoric acid and (d) as a stabilizer to inhibit the decomposition of hydrogen peroxide, a quaternary ammonium salt represented by the formula: **(See formula)** wherein R is a radical of an aliphatic compound containing from 8 to 21 carbon atoms and which is an alcohol or alkoxy, hydroxy, or propyl group and R2 to R4 are selected from the group consisting of an alcohol group or an alkoxy group 1 to 2 carbon atoms, a benzyl group and its derivatives, or a pyridyl group and its derivatives, and keeping said stainless steel surface in contact with the pickling solution until the desired part of the surface has been chemically dissolved and cleaned .
