Pickling & Passivation
Pickling is a process used to remove all impurities from steel surfaces. It involves immersing the component in a specially formulated, acidic pickling solution.
Passivation is the formation of a protective passive layer that reduces the chemical reactivity of a metal’s surface. The layer can be formed in a natural way caused by both oxygen and humidity.
Due to the fact that there is a risk of corrosion until the passive layer has completely formed, we speed up this process to a matter of minutes with our special blend of passivation chemicals.
A protective passive layer can only be formed on pure metal surfaces. So pickling is an essential step that needs to be taken before passivation can occur.
