Abstract

Método para controlar la composición de una solución de decapado, caracterizado porque en el decapado para acero inoxidable que emplea un baño de sulfato férrico-ácido fluorhídrico, el potencial de oxidación-reducción de la solución de decapado se mantiene en un intervalo previamente determinado añadiendo peróxido de hidrógeno y ácido sulfúrico en la solución de decapado.Method for controlling the composition of a pickling solution, characterized in that in pickling for stainless steel that uses a ferric sulfate-hydrofluoric acid bath, the oxidation-reduction potential of the pickling solution is maintained in a previously determined range by adding peroxide of hydrogen and sulfuric acid in the pickling solution.
