PASSIVATION

Passivation

The term "passivation" quite simply means rendering a surface passive, or not prone to corrosive attacks when subjected to corrosive elements. In the case of stainless steel, the passivation layer is created naturally after the metal is fabricated and comes into contact with air and water. While this layer does offer some corrosion-resistant properties, the nature of stainless steel fabrication can lead to problems.

 

Even when great care is taken, cutting, bending, welding and polishing tools can leave behind particles that get embedded in the surface of stainless steel tanks and other equipment. These surface disparities act as initiation sites for corrosive attack much like contamination in a paint job can cause paint to flake and the base metal to rust.

 

Hard Chrome is a PA specialist covering the polishing and passivation needs of customers in York, Harrisburg and across the state. We have been in business since 1988 and are experts in industrial stainless steel passivation. Our passivation process helps ensure that your steel parts are clean and free from surface contamination and helps your stainless steel parts last longer.

 

How Passivation Is Performed

 

Our industrial passivation involves cleaning the surface of your steel components to remove all particles and contamination. Depending on the nature of your materials, we will choose the best etching solution (typically citric acid). This acid dissolves all non-passive particles and disparities on the surface of your materials or parts and renders them less susceptible to corrosion.

 

At Hard Chrome Specialists, we have more than 14,000 square feet of space and can handle any size of passivation job. Our customers have come to trust our knowledge and experience for all of their metal surface finish needs. When you contact us, we sit down and discuss your materials and applications with you. We don’t believe in a "one size fits all" mentality — your industrial passivation project deserves a unique solution that gives you the passive surface your products and materials need.
