Electropolishing of stainless steel

Electropolishing of stainless steel

Electropolishing of stainless steel that maximizes its performance.

**Features of Stainless Steel Electrolytic Polishing** ◆ Achieves a Clean Surface By dissolving the stainless steel surface, it removes foreign substances and fine dirt that are difficult to eliminate through physical polishing, resulting in a clean surface with good washability. ◆ Provides High Corrosion Resistance As a result of forming a more robust and stable passive film rich in chromium, it results in a surface with high corrosion resistance. ◆ Produces Gloss It results in a surface with a different roughness and gloss compared to buff polishing. It can be used as an alternative to buff polishing or in combination with it. ◆ Allows Polishing of Areas Not Possible with Buff Polishing There are areas that cannot be polished due to the size of the polishing tool in physical polishing. Electrolytic polishing can effectively polish such fine areas. ◇◇ For more details, please download the catalog or contact us ◇◇

Surface treatment processing SUS steel coloring treatment

Surface treatment processing SUS steel coloring treatment

Let's change the world's "values" together through the coloring of stainless steel products!

○ What is stainless steel oxidation coloring? It is a technique that changes the thickness of the stainless steel oxide film to create interference colors (light and a transparent thin film) through passivation (oxidation film), where a participating film exists on SUS material, and when viewed, the colors appear to change like a CD due to light refraction. ○ The establishment of new coloring technology has doubled corrosion resistance and contributes to the enhancement of color decoration and identification in products across various fields. ○ Even the same product can change its impression if the color changes. → This leads to a departure from commoditization. ○ Creating a new category leads to differentiation in brand awareness.

What is electropolishing? What is Super Shiner A2?

What is electropolishing? What is Super Shiner A2?

A clear explanation of the differences between denken and electropolishing, as well as passivation and other related topics!

The method commonly referred to as "Denken," which is performed by our hometown processing partners by default, differs from "electrolytic polishing." However, the effect of "improving corrosion resistance" is the same. First, "Denken" refers to "Super Shiner A2," which is produced by Chemical Yamamoto Co., Ltd. The slogan for Super Shiner A2 is "SUS304 achieves corrosion resistance comparable to SUS316." So, why does using Super Shiner A2 improve corrosion resistance? The key phrase is "ultra passivation." *For more detailed information, you can view the related links. For more details, please download the PDF or feel free to contact us.*

Electrolytic Polishing EP

Electrolytic Polishing EP

Electropolished finish that enhances the sanitary properties and corrosion resistance of stainless steel containers.

The finishing of each series is typically done with a standard buff polishing finish, except for some products, but electropolishing is possible to enhance sanitary properties and corrosion resistance. Electropolishing is a method that smooths the surface of stainless steel by chemically and electrically dissolving metal ions from the metal surface in an electrolytic solution. This results in a uniform and high-quality finish. Electropolishing can be applied to almost all parts that come into contact with liquids, including containers and sanitary components.

Stainless steel coloring technology

Stainless steel coloring technology

Stainless steel breaks away from the fixed concept of being silver! A technology that allows stainless steel to be colored.

The "stainless steel coloring technology" is a technique that creates interference colors (light and a transparent thin film) by changing the thickness of the oxide film on stainless steel. Since there is an oxide film on SUS material, the color appears to change due to the refraction of light, similar to a CD, allowing for a change in the color of the stainless steel itself, unlike traditional coloring methods. We have established a new industrial coloring technology that reduces color variation between lots, which was not possible with conventional techniques, and combines it with a new method that is expected to reduce color unevenness compared to traditional coloring methods. 【Features】 ■ A technology that colors the stainless steel itself ■ Improved decorative and distinguishable color tones ■ Can double corrosion resistance ■ Planned to be available in over 20 colors ■ A film in the nanometer range that does not affect dimensional tolerances *For more details, please refer to the PDF document or feel free to contact us.

Technical Data: Corrosion Resistance of Electropolished Stainless Steel

Technical Data: Corrosion Resistance of Electropolished Stainless Steel

One reason is that the corrosion resistance improves after electropolishing.

Electropolishing is widely used as a finishing process for stainless steel not only because of its excellent luster but also because it improves corrosion resistance after electropolishing. By electropolishing, the altered layer and temper scale caused by prior machining are removed, along with contaminants on the surface (such as debris and dirt from processing), resulting in a cleaned surface. Additionally, through electropolishing (anodic dissolution), a thin oxide film is formed on the surface, creating a passive film. This passive film has a higher chromium content than the base material (the stainless steel substrate), resulting in a coating with good corrosion resistance. Furthermore, by eliminating surface roughness, it becomes more difficult for debris and dirt to adhere to the surface after electropolishing, which also contributes to improved corrosion resistance.
