Do stainless steel cable trays need passivation
Stainless steel is valued for its durability and ability to resist rust, but it can still gain from additional protection. In marine, industrial, or medical. It follows that proper passivation enhances corrosion resistance in stainless steel and provides reliable performance over the long term in many applications. Understanding the chemistry, process, and regulatory requirements that prevent costly FDA audit failures Based on 23+ years supplying passivation chemicals to medical device manufacturers. Stainless steel is only “stainless” when the surface oxidizes with chromium and other elements to develop a protective film that resists further oxidation. This protected oxide film is considered a passive surface. To passivate stainless steel, a minimum of 10.
