It should undergo a passivation stage to ensure that fabrication or component corrosion resistance is optimized before delivery. Employing high oxidizing agents all surfaces are either sprayed or immersed in a solution that oxidizes the Chromium. This rapidly forms the inert layer on the material and creates the critical surface property relied upon in service. Several passivation methods are employed depending on the Alloy, pre-treatment, and type of application. ISO 15730 and ASTM A967 Stainless Steel Passivation specification details each process in depth.

At Hidayath, we offer specialized passivation services. This process boosts the corrosion resistance of stainless steel parts. Passivation chemically restores the chromium oxide layer. This layer protects against rust and contamination in industrial, marine, and hygienic settings.

What is Passivation and Why is it Important?

Passivation is a chemical treatment that cleans stainless steel. It removes contaminants like free iron, heat tint, and oxide scale. This process re-forms the protective chromium oxide film. As a result, stainless steel components become highly resistant to corrosion. Passivation is crucial after welding, fabrication, machining, or pickling.
