Stainless Steel Electropolishing
Stainless Steel Electropolishing is an electrochemical process sometimes referred to as “reverse plating” that works to passivate and restore the natural corrosion resistance of stainless steel.
Stainless Steel Electropolishing is a surface finishing technique that utilizes an electrolyte mixture that is positively charged using DC power to dissolve a small layer off of the exterior “skin” of stainless steel parts.
Why electropolish stainless steel?
Trace contaminants are often left behind during the manufacturing process that can compromise the natural corrosion resistance of stainless steel. Stainless steel alloys that have been passivated through electropolishing have an improved surface finish that enhances aesthetics, makes stainless steel components easier to clean and sterilize and restores the corrosion resistance of the metal.
What types of industries utilize stainless steel electropolishing?
Stainless steel electropolishing is utilized in a wide array of industries and has become a crucial step in the manufacturing process for a variety of stainless steel products and parts.
Some of the most common industries that utilize stainless steel electropolishing are:
- Semi-conductor manufacturing
- Aerospace manufacturing
- Medical device manufacturing
- Pharmaceutical and research laboratory equipment manufacturing
- Marine product manufacturing
- Food service product manufacturing
Electropolishing can remove imperfections from stainless steel parts including:
Electropolishing can solve complex corrosion issues. Learn about how NEE helped Battery Wharf restore the corrosion resistant layer and architectural beauty of the stainless steel architectural accents at Battery Wharf in Boston, MA.
New England Electropolishing is one of the few metal finishers in the U.S. to concentrate exclusively on stainless steel electropolishing. By focusing exclusively on stainless steel electropolishing since 1985, NEE has developed a reputation as a leader in the industry. NEE is driven to exceed customer expectations and is widely recognized for their ability to achieve a level of quality and consistency that other metal finishers simply cannot.
