Information about Nitric Acid Passivation

To start process of Nitric Acid Passivation, the mechanics need to remove the scales first. They do it easily with the special technique called ‘pickling.’ The process is also termed as mechanical abrasion. It takes some time as removing the scales if often a tough task. <br>

  1. Though stainless steel has a natural ability for self- passivation, there occur some situations when steel is exposed to a natural environmental situation. That situation brings it sufficient oxygen to encourage corrosion after some time. This condition is not good for the longevity of the metal.

  2. The situation can be improved by the processes of passivation and pickling. These two are the trusted ways to improve the natural properties of the metal. Though many acidic combinations work well for the same, Nitric Acid is trusted by many industries. Before trying the steel passivation with Nitric Acid, the manufacturers need to decide if the process is necessary at all or not.

  3. To start process of Nitric Acid Passivation, the mechanics need to remove the scales first. They do it easily with the special technique called ‘pickling.’ The process is also termed as mechanical abrasion. It takes some time as removing the scales if often a tough task. The process often includes hydrofluoric/Nitric acid mixtures. However, there are some differences here.

  4. However, the industries that use Nitric Acid Passivation need to make sure that all pollutants or contaminants are removed completely before applying Nitric Acid. It is capable of cleaning or removing iron contamination from the surface.
