STAINLESS STEEL PICKLING IN AN OXIDIZING, ELECTROLYTIC ACID BATH

摘要

A pickling process designed for pickling a metal strip such as a stainless steel strip reduces the amount of HF and/or HNO3. The strip is immersed in at least one first pickling tub that contains a mixture of an acid such as H2SO4, an excess of at least one oxidizing agent, and includes electrodes that may apply a current to the strip that runs through the mixture.
