Etching technique with hydrogen peroxide for stainless steels.

摘要

A method for etching a stainless steel strip continuously comprising the steps of: a) immersing said strip in a tank pre-pickling containing said tank a solution of pre-stripping comprising sulfuric acid and hydrofluoric acid; b) immersing said strip after step to a pickling tank, containing said tank an etching solution composed of sulfuric acid, hydrofluoric acid and stabilized hydrogen peroxide and c) removing heat from the pickling solution of step b.
