How to Choose the Right Chemistry for Your Metal Finishing Process
In an industry where production time, volume, and quality are critical, it’s increasingly important to ensure metal parts obtain desired results and meet specifications established. Since metal parts cleaning is quickly becoming the industry standard, facility managers must become well versed in the extensive cleaning processes and chemistries available that will provide the performance level required. It is also essential that they must learn the differences between aqueous and solvent cleaning solutions and the advantages and disadvantages of using each approach.
With that being said, it takes time and effort to find the right chemistry that meets your needs. Settling for anything less could be dangerous. Luckily, our Global Product Line Manager, Joe McChesney, can help!
Read his latest article “Choosing the Right Chemistry” which will teach you everything you need to know about finding which chemistry is right for your process.
A Closer Look at Stainless Steel Passivation And How You Could Benefit From It
There are many ways to keep stainless steel protected from corrosion. One popular way is to utilize a method called passivation. You might be wondering how that works or what it means. We’ve got answers!
Simply put, passivation, unless otherwise specified, is defined as the chemical treatment of stainless steel with a mild oxidant, such as a citric acid solution, for the purpose of the removal of free iron, or other foreign matter. Citric acid passivation treatment of stainless steel is intended to improve the corrosion resistance of parts made from stainless steels of all types.
The formation of the protective passive film on a stainless steel, also called passivation, will occur spontaneously in air when the stainless-steel surface is free of oxide, free iron, and other contaminants. After passivation with this process, parts are rinsed in clean water, and no further chemical treatment is required.
To learn more about the benefits of passivation, we invite you to download our informative document that explores how the process works and which chemistries work best. Additionally, if you are a veteran to passivation, you might wonder if the passivation has been done correctly. At KYZEN, we offer a Copper Sulfate Test Kit that provides the answers you need!
