PASSIVATION - PSV-72 - Passivation Overview: . Passivation is a crucial chemical process used to enhance the corrosion resistance of metals, particularly stainless steel and other alloys. The process involves creating a protective oxide layer on the surface of the metal, which helps prevent rust and other forms of corrosion. Passivation is commonly used in industries where metal components are exposed to harsh environments, such as in the chemical, pharmaceutical, and food processing sectors. - What Does PSV-72 Refer To? . PSV-72 is likely a specific reference within the context of passivation processes or equipment. It could pertain to a standard, a procedure, or even a particular piece of equipment. Without additional context, several interpretations are possible:
