ISO 15730 Standard of Electropolishing Stainless Steel
Set by the International Organization for Standardization (ISO), ISO 15730 is the global standard for smoothing and passivating stainless steel by electropolishing. As a major provider of metal finishing services for manufacturers worldwide, Able Electropolishing consistently meets the high standards set by ISO 15730.
Smoothing & Passivating Stainless Steel
Electropolishing is a consistent, effective method for passivating stainless steel, and one that Able Electropolishing has been practicing and refining since 1954. The quality of our process enables us to meet the standards of ISO 15730.
As a reverse-plating process, electropolishing is a metal finishing service that removes a uniform, controlled amount of surface material from a metal part. Doing so eliminates the imperfections and embedded contaminants that serve as initiation sites for corrosion, which compromises the usability and the longevity of a part.
After electropolishing, stainless steel parts are left with a smooth microfinish that is highly passive and corrosion-resistant.
Electropolishing VS. Passivation
Passivation is useful for removing free iron and contaminants from stainless steel and for applications where maintaining part dimensions and physical properties is critical.
When a higher level of corrosion resistance and the removal of surface defects like burrs and microcracks is needed, electropolishing can be a better option.
Electropolishing removes a microscopically precise layer of surface material, controlling removal as close as +/-.0001″, depending on the alloy. This degree of precision and consistency, along with the ability to remove a variety of surface imperfections in one process, is why electropolishing is so often specified for critical parts used in the medical field, aerospace, pharmaceutical, and other industries. Electropolishing is a one-stop process for a micro-smooth, ultraclean, corrosion and pathogen-resistant surface finish – with 30 times more corrosion resistance than passivation.
Electropolishing often times can eliminate the need for additional metal finishing processes like hand deburring, tumbling, pickling, and cleaning. Learn more about passivation vs. electropolishing.
By electropolishing stainless steel parts in accordance with ISO 15730, we provide a better, more passive finish that meets or exceeds industry standards.
