After decontamination from possible contaminating elements, stainless steel remains without any protection, and therefore exposed to aggressive external attacks.
Passivation enables to restore the chrome oxide surface layer which had been depleted or contaminated.
This treatment is essential to guarantee the stainlessness of stainless steel. A good passivation takes about from 2 to 8 hours and has to act on the whole surface.

A passivating product is also required for a regular maintenance of the stainless steel manufacture surface.
