Update PASSIVATION Instructions

2024-08-18

Passivation is a chemical process used to remove free iron, dirt, oil, grease, and other contaminants from the surface of stainless steel parts. This process helps to improve the corrosion resistance of the metal and ensures that the part meets industry standards for cleanliness.

At ESD team, we follow a strict set of passivation operation instructions to ensure that the parts we produce are of the highest quality. Our passivation process begins with a thorough cleaning of the parts using a mild detergent and water to remove any surface contaminants. The parts are then thoroughly rinsed and dried to prepare them for the passivation solution.

The passivation solution we use is typically a nitric acid-based solution that is specific to the grade of stainless steel being treated. The parts are immersed in the solution for a predetermined amount of time, typically between 20-30 minutes, depending on the size and complexity of the parts.

After the parts have been immersed in the passivation solution, they are rinsed thoroughly with water to remove any remaining acid and contaminants. The parts are then dried and inspected to ensure that the passivation process has been successful.

Our team is highly experienced in performing passivation operations and we take great care to ensure that all parts are treated correctly to meet industry standards. We understand the importance of surface treatments in the manufacturing process and strive to provide our customers with the highest quality metal parts possible.

In addition to passivation, we also offer a range of other surface treatments including anodizing, plating, and powder coating to meet the specific needs of our customers. Our goal is to provide comprehensive manufacturing solutions to our customers and ensure that their metal parts meet the highest standards of quality and performance.
