What is electro polished stainless steel?

What is electro polished stainless steel?

Electropolishing stainless steel is a “reverse plating” process that uses an electrochemical solution to remove the outer skin of a metal part. Electropolishing stainless steel significantly, especially 300 and 400 series stainless steel, improves a part’s corrosion resistance, leaving it with a lasting bright finish.

What is electro polishing process?

Electropolishing is an electrochemical finishing process that removes a thin layer of material from a metal part, typically stainless steel or similar alloys. The process leaves a shiny, smooth, ultra-clean surface finish. Both are non-mechanical, chemical processes, but only electropolishing uses electrical current.

Does electropolishing require passivation?

Chemical passivation is required after electropolishing, since electropolishing passivates the surface only to a condition typically attained by phosphoric acid. Chemical passivation will improve the corrosion resistance of all austenitic stainless steel surfaces, no matter the surface profile or roughness condition.

What is electropolishing machine?

Electropolishing equipment produces a bright, corrosion-resistant, highly-polished surface on stainless steel and other metals. Quality electropolisher machines ensure repeatable, micro-tolerance surface roughness finishing that can be easily validated to regulatory and industry requirements.

How is the material removed in electropolishing process?

How is the material removed in Electropolishing process? Explanation: Material in Electropolishing is removed by anodic dissolution process.

Does electropolishing prevent rust?

Electropolishing removes the impurities on the metals surface, while producing a uniform finish that is occlusion free and microscopically smooth. By drawing out the impurities you prevent corrosion and rust.

What kind of process is electropolishing stainless steel?

Electropolishing Stainless Steel is an electrochemical process often referred to as “reversed plating”. Electropolishing removes material at a controlled rate and can be controlled to .0002” accuracy.

Who is the leader in electropolishing stainless steel?

New England Electropolishing is one of the few metal finishers in the United States to focus exclusively on electropolishing stainless steel. NEE is an industry leader serving a variety of industries such as medical device, semiconductor, laboratory, industrial, and food service.

How does electropolishing work and how does it work?

Instead of adding a thin coating of positively-charged metal ions, electropolishing uses electric current to dissolve a thin layer of metal ions into an electrolyte solution. How does electropolishing work? In electropolishing, the metal part or work-piece serves as the positively-charged anode.

How much material can be removed in an electropolishing process?

For an electropolishing process with longer cycle time and amp-minutes, as much as 0.003″ to 0.005″ of material may be removed. The longer the electrical current is applied, the more material is removed but the less uniform the resulting surface finish.
