Chemical Cleaning

Passivate

Passivation is a chemical treatment on metallic surfaces for cleaning and added corrosion protection. The purpose of passivation is for the removal of “free iron” and other exogenous foreign material from a metallic surface. During passivation a thin transparent oxide layer is formed on the metallic surface .This oxide layer is a protective surface film that inhibits chemical and atmospheric corrosion. Passivation is primarily applied to stainless steels and titanium; however other metals can be passivated either by chemical treatments or other means.

Why Passivate?

Contrary to popular belief, stainless steel can corrode, especially heat-treatable stainless. During the production process using martensitic stainless steel, trace amounts of iron are introduced into the surface of the stainless form machining, forming, rolling or stamping. This iron is very susceptible to corrosion. Once the iron corrodes it can actually penetrate into the base steel. Passivation dissolves the iron and leaves the surface passive.
