Passivation of stainless steel

The passivation of stainless steel is a surface conversion chemical treatment that aims to eliminate contamination by other materials (particularly iron particles collected during machining operations), which would jeopardize the corrosion resistance of the manufactured items and improve the environmental resistance of the given metal.

Our company is active in the sector, offering passivation treatments of stainless steel and metal alloys, carried out on metal pieces of different types quickly and according to the reference specifications ASTM A967-05(14) and AMS-QQ-P-35 C (15).

Because the passivation of stainless steel is crucial

When performing a passivation treatment of stainless steel it is essential that the material does not come into contact with any other type of contaminant prior to the formation of the passivation layer.

During the passivation treatment, when the steel is in contact with an oxygen-rich environment, chromium, being a very reactive material, tends to form very stable oxides and hydroxides. In this sense, this type of treatment suppresses undesired reactions, which can lead to the corrosion of stainless steel.

In fact, such treatment ensures that an optimal result is achieved very quickly and with the use of only one surface process.

This is a crucial process

The levels of resistance to corrosive phenomena of stainless steels and other metals depend strictly on their surface conditions and in particular on the presence or absence on their surface of a layer of oxides known as the “passive layer”.

With this in mind, passivation of stainless steel is, therefore, a key process for the production of metal components that are highly defined both functionally and aesthetically.
