Electrolytic polishing of stainless steel to maximize 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 cleanability. ◆ Provides high corrosion resistance As a result of forming a more robust and stable passive film rich in chromium, the surface exhibits high corrosion resistance. ◆ Produces a glossy finish 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. ◆ Enables polishing of areas that cannot be buff polished There are areas that cannot be polished due to the size of the polishing tools in physical polishing. Electrolytic polishing allows for the polishing of such fine areas. ◇◇ For more details, please download the catalog or contact us ◇◇

basic information
Electrolytic polishing is a polishing method that achieves a polishing effect by flowing direct current through an electrolyte solution between the product, which is positioned on the positive side, and the counter electrode on the negative side, thereby dissolving the metal surface. 【Applicable Materials】 - Austenitic (SUS304, SUS316, etc.) - Ferritic (SUS430, etc.) - Martensitic (SUS410, SUS420, etc.) - Duplex (SUS329, etc.) - Precipitation hardening (SUS630, etc.)* - For other steel types, please inquire. *The finish may vary depending on the heat treatment condition. 【Processing Capability】 - Proven track record of tens of thousands of items, from very small to extra-large products. - Capable of handling everything from single prototype pieces to mass production. - Large lot items can also be accommodated with fully automatic electrolytic polishing equipment. ◇◇ For more details, please download the catalog or contact us ◇◇

[Surface Treatment Example] Electrolytic Polishing of Pipe Interior This is a case of treatment where electrolytic polishing was applied to the interior surface of a pipe. Before electrolytic polishing, there were buff polishing marks and discoloration, but after electrolytic polishing, a clean and smooth surface was achieved with the buff polishing marks and discoloration removed.

Company information
Our company has been engaged in surface treatment technology for over 60 years, incorporating the philosophies of ISO 14001 and ISO 9001 into our processes, ranging from metal houseware products to semiconductor manufacturing equipment components. Through thorough quality control and technological development, we provide surface treatment processes that meet the demands of the times. Our electrolytic composite polishing has received high praise, including a letter of appreciation for contributing to the completion of the Japan Proton Accelerator Research Complex (J-PARC), a high-intensity proton accelerator facility constructed jointly by the Japan Atomic Energy Agency (JAEA) and the High Energy Accelerator Research Organization (KEK). We perform various surface treatments that maximize the advantages of different metal materials, including electrolytic polishing, electrolytic composite polishing, coloration of stainless steel and titanium, and pickling. In recent years, we have also been involved in surface treatment processing for materials such as magnesium, aluminum, and titanium. Leveraging the expertise in surface treatment developed in the Niigata Prefecture Tsubame-Sanjo region, which is well-known for metal processing, we are here to assist you in solving your problems.
