How Does Stainless Steel Passivation Process Work? What is the meaning of passivation and how does it work? How to passivate the parts of the stainless steel after machining operations? These are a few questions asked by the companies or manufacturers regarding the Stainless Steel Passivation Process. What is the passivation of stainless steel? Passivation is a commonly used process for mental finishing to prevent corrosion. In stainless steel, either nitric acid or citric acid is used for the passivation process in order to Remove Rust from Stainless Steel. The chemical treatment results in the formation of a protective oxide layer with less possibility to chemically react with air and lead to corrosion. Passivated stainless steel prevents rust. What is the meaning of passivation stainless steel? The chemical treatment of stainless steel with a mild oxidant with solutions such as nitric acid or citric acid in order to remove the free iron or other foreign matter. It maximizes the corrosion resistance of stainless steel, helping it to stay rust-free for much longer. Why passivate stainless steel? Passivation is the best practice for all grades of stainless steel. It encourages the natural formation of a protective layer on the stainless steel, protecting the surface from contamination. Without passivation, iron present in stainless steel can easily come in contact with pollutants that may lead to corrosion and ultimately rust. Any stainless surface can be affected by rust over a period of time, so it is vital to make sure every part of the stainless steel is covered during the passivation process. Given below are the benefits you can achieve through passivation: ● ● ● ●
The protective barrier of chemical film against rust Increased life of the product Removal of contamination from the product surface Reduced requirement for maintenance
How does passivation work? Stainless steel is an iron-based alloy, usually consisting of iron, chromium and nickel. Stainless steel gets its corrosion-resistant characteristics from the chromium content. Chromium, when it comes in contact with oxygen, develops a thin layer of chromium oxide that covers the surface of the stainless steel and protects the iron from rusting. The reason behind passivation is to optimize and augment the formation of the chromium oxide layer. Thus, if you want to ensure a safer, environmentally friendly and cost-effective Stainless Steel Passivation Process, then Reba Safer Chemical is here to help.
