Materials

Each of our services may be applied to a wide range of materials, however, a specific material may not be suited for a specific treatment. Please review the link to your specific material and learn which services can be performed on your material. Contact us with any questions regarding which materials are best for electropolishing, passivation metals, mechanical polishing and more.

Advantages of Passivation of Titanium

Titanium provides high specific strength, good high temperature properties and exceptional corrosion resistance. Titanium's corrosion resistance is provided by a tightly adherent TiO2 film. Its excellent corrosion resistance makes titanium an option for chemical processing equipment, marine equipment, biomedical implants and much more.

While titanium possesses excellent corrosion resistance, it still may be affected by surface contaminates and oxides which may be removed by passivation and finishing.

Benefits of Passivating Titanium

Titanium can be mechanically polished to improve surface finish, reduce product adhesion and to improve cleanability. Harrison Electropolishing can mechanically polish titanium and certify surface finishes as low as 4 Ra micro-inches. The passivation of titanium does not affect or improve its corrosion resistant oxide layer. However, passivation of titanium does remove iron and other surfaces contaminates.

AL-6XN Stainless Steel Electropolishing & Passivation

AL6XN stainless steel is a registered trademark of Allegheny Ludlum. AL6XN standard stainless steel possesses excellent general corrosion resistance with exceptional resistance to crevice corrosion, chloride-induced corrosion, pitting, and stress corrosion. The properties of AL6XN material, much like stainless steel, may be degraded by real world fabricating and handling operations. Electropolishing can be used to reverse these adverse effects and to improve the corrosion resistance of AL6XN. Further details can be found in our discussion of electropolishing.

The corrosion resistance of AL6XN may also be improved by passivating the surface. Harrison Electropolishing can mechanically polish AL6XN and certify a finish as low as 4 Ra micro-inch.

During the passivation of AL6XN, the surface of a part is chemically treated with a chemical oxidant. The chemical passivation treatment removes free iron and other foreign contaminants, allowing the AL6XN to perform and resist corrosion as it is engineered to do.

We have performed passivation treatments on AL6XN with excellent results for a number of years. We have the capacity to passivate AL6XN components of all sizes. Harrison Electropolishing will perform chemical passivation treatments in compliance with ASTM specifications or your industry or company specific chemical passivation standard.

Carbon Steel Mechanical Polishing

During discussions about metal finishing and polishing the applications for carbon steel are often overlooked. The truth is that carbon steel, with its countless uses, is often polished. Carbon steel is frequently mechanically polished to improve the surface finish, reduce product adhesion or improve cleanability.

Harrison Electropolishing can mechanically polish carbon steel to improve its surface finish. All surfaces, from cast to finely machined, may be mechanically polished to achieve a specified surface finish. Commonly polished components include exchanges, valves, mixers, product transfer piping and reactor piping. Contact us today regarding our carbon steel polishing services.

Polishing Hastelloy

polishing hastelloy Hastelloy, a registered trademark of Hayes International, is a nickel-based alloy with high chromium and molybdenum. Hastelloy alloys exhibit high strength and excellent resistance to pitting, crevice corrosion and stress corrosion cracking. The properties of Hastelloy, much like stainless steel, are degraded by real-world fabricating and handling operations. Electropolishing can be used to reverse these adverse effects and to improve the corrosion resistance of Hastelloy. Further details can be found in our discussion of electropolishing.

The corrosion resistance of Hastelloy may also be improved by passivating the surface to remove contaminates which adversely affect its corrosion resistant properties.

Harrison Electropolishing can mechanically polish Hastelloy and certify finishes as low as 4 Ra micro-inch.

Harrison Electropolishing can oxygen clean and chemical clean a wide range of Hastelloy components. Contact us to discuss which service is best for your Hastelloy components.

Stainless Steel Mechanical Polishing & Oxygen Cleaning

Stainless steel combines desirable mechanical properties with proven corrosion resistance. Stainless steel mechanical polishing is often chosen for applications within harsh environments. Published data is available to verify the performance of specific alloys within specific environments. Despite being used within appropriate environments, stainless steels may and do fail by corrosion.

cb materials stainless steel 1 All stainless steels are iron-based alloys (minimum 50% iron) and have at least 10.5% chromium. The chromium content is the key to stainless steel's basic corrosion resistance. When the chromium is exposed to oxygen, it spontaneously forms a passive oxide layer. This passive oxide layer is very thin, yet it prevents further diffusion of oxygen into the base material and thus prevents corrosion. Stainless steel electropolishing can be used to improve the corrosion resistance of stainless steel by enhancing the thickness and the properties of this passive oxide film. Further details can be found in our discussion of electropolishing stainless steel and other metals.

The corrosion resistance of stainless steel may also be improved by passivating the surface.

Harrison Electropolishing can mechanically polish stainless steels and certify a finish as low as 4 Ra micro-inch.

Harrison Electropolishing can oxygen clean and chemical clean a wide range of stainless steel components.

Harrison Electro Polishing, the Leading Electropolishing, Passivation, Oxygen Cleaning & Mechanical Polishing Company World Wide.

Electropolishing is an electrochemical process by which surface material is removed by anodic dissolution. Electropolishing removes surface material, beginning with the high points within the microscopic surface texture. By removing these points, the electropolishing process will improve the surface finish of a metal such as stainless steel, nickel, and Hastelloy, leaving a smoother and more reflective surface. Common parts and components electropolished include tanks, piping, fittings, rods, discs, large parts & surfaces, and more.
