PASSIVATION 72
It seems you're referring to "Passivation 72." Passivation is a process used to protect metals from corrosion. When a metal is passivated, a thin layer of protective material forms on its surface, preventing further corrosion. "Passivation 72" might refer to a specific type of passivation process or a product related to passivation, but without further context, it's difficult to provide specific information. If you could provide more details or clarify your question, I'd be happy to assist you further.
