Frequently Asked Questions (FAQs)

Everything You Need to Know About Pickling & Passivation Services

What is pickling in stainless steel treatment?

Pickling is a chemical process that removes surface contaminants, such as oxides, scale, and rust, from stainless steel using acids like nitric and hydrofluoric acid. This restores the metal’s corrosion-resistant surface, making it clean and ready for further use or finishing.

What is passivation and how is it different from pickling?

Passivation is a process that enhances the corrosion resistance of stainless steel by removing free iron from the surface and allowing a thin oxide layer to form. Unlike pickling, it doesn’t remove scale or discoloration but helps restore and protect the passive layer without affecting the metal itself.

When should pickling be done?

Pickling is recommended after welding, heat treatment, or fabrication processes that cause oxidation or discoloration. It should be done when there is visible scale, heat tint, or rust on stainless steel components.
