Stainless Steel Etching

Etching of stainless steel is a chemical process of removing the oxide layer and
impurities (e.g., residues from welding or machining) from the surface of stainless
steel. The aim is to restore its corrosion resistance and achieve a
uniform, clean finish. Here is the most important information:

What does stainless steel etching involve?

Etching involves the use of special chemical solutions that react with the
surface of stainless steel, removing:

• welding scale (chromium and iron oxides),
• dirt and material residues,
• surface layers of metal that could promote corrosion.

Etching methods

Immersion etching – the steel is immersed in a pickling solution bath (for
elements with regular shapes).
