Veelgestelde vragen over beitsen & passiveren

The difference between pickling and passivation lies in the treatment of stainless steel surfaces. Pickling removes weld seams, discoloration, and other irregularities using strong acids. In contrast, passivation restores the protective layer of stainless steel with a nitric acid solution.

Operations on stainless steel, such as welding, bending, or external contamination, always damage or weaken its protective chromium-iron oxide layer. To restore this oxide layer and make the stainless steel passive again, pickling and passivation are essential treatments. This process should always be performed, as untreated stainless steel will inevitably cause problems during use.
