Various organizations and groups present specifications for the processes involved in metal finishing treatments. They supply exact and stringent standards finishing companies rely on to provide the best products possible.
For the passivation of stainless steel components, the document for the passivation specification is known as ASTM A Passivation is the overlaying of a substrate or base layer with another metal.
The intent is to remove any foreign or undesirable traits and improve the corrosion resistance of the stainless steel component. Chemical passivation has as its major goal to provide a layer of protection over the base metal.
