Abstract

A product for pickling surfaces of chromium-nickel steels and chromium steels contains sulphuric acid, phosphoric acid or mixtures thereof and Fe(III) ions, the product additionally containing fluoboric acid. Using this product, it is possible to pickle surfaces of chromium-nickel steels and chromium steels in such a way that undesired oxide coatings, contaminations and tarnishing colours are removed. In the case of this product, the use of hydrofluoric acid or hydrofluoric acid in addition to nitric acid is unnecessary.
