Passivated stainless steel

Passivation is a non-electrolytic finishing process that makes stainless steel more resistant to rust. Although passivation arises spontaneously on the surface of stainless steel, it is sometimes necessary to favor the process with an oxidizing acid. In this stage, surface metal is not removed, but rather a passive layer is created on the part. In many cases, it is a prerequisite to pickling the part with mixtures of nitric and hydrophloric acid that allow the removal of thermocolouration stains by welding from the surface of the part.

The entire process of passivation of stainless steel is carried out by complete immersion of the parts in a battery of vats, each with different compositions and missions.
