In theory, the chrome layer will not fade under most working conditions. The stability of chrome metal itself is extremely high, and the chromium oxide layer on its surface can effectively prevent the external environment from corroding the chrome layer. Therefore, the chrome layer can usually maintain its original luster and color for a long time and is not easy to fade.

The hardness of the chrome plating layer of industrial chrome-plated rollers is usually between 800 and 1000 Vickers hardness (HV). This hardness range depends on the specific conditions of the chrome plating process, including current density, temperature, plating solution composition, etc.

Usually, industrial chrome-plated rollers are plated with a layer of chrome, and the thickness is adjusted according to the use requirements. Single-layer chrome plating can already provide quite strong wear resistance and corrosion resistance, which is suitable for most industrial applications.
