Spring Corrosion and Prevention

What is Corrosion?

Corrosion is the deterioration of a metal and its properties as a result of extended exposure to a substance that negatively reacts with metal. The level of corrosion protection required is application-specific, and the type of corrosion will also vary. Carbon steels, such as music wire, spring steel, and chrome vanadium that do not have a coating, are the most at risk for corrosion. Stainless steels and exotic alloys offer protection from various agents.

How to Protect Against Corrosion

Material selection is one method for combating corrosion. In some cases, changing materials is not possible because of the forces, stresses, or other design parameters required by the application. Coatings offer a means to supplement corrosion protection without changing materials. Selecting a protective coating for parts may be the only option to achieve the desired lifecycle and may be more cost-effective than substituting material.

Associated Spring RAYMOND offers a variety of materials and coating options for the entire spring portfolio. SPD™ Standard Gas Springs, IGS™ Extended Life, and Raymond® Mechanical Struts are available in stainless steel and high-quality finishes, making them highly resistant to corrosion. Coatings are available with salt spray resistance up to 1,000 hours per ASTM B117.

In addition to a broad material offering, AS RAYMOND offers a variety of secondary processes, including electropolishing, to improve surface finish and meet the application's aesthetic and corrosion resistance requirements. AS RAYMOND’s engineers can help to define the best material and coating for OEM applications. Fill out a contact form for assistance.
