Hardness of hard chromium plating on drum

The hardness of hard chrome plating can vary depending on the thickness of the plating and the underlying substrate, but typically it ranges from 68 to 72 Rockwell C (HRC). This level of hardness makes hard chrome plating well suited for applications that require a high degree of wear resistance and durability, such as rollers used in metal processing, printing, and paper making.

It's important to note that hardness is just one of many factors that can influence the performance of hard chrome plating on rollers. Other factors such as adhesion, surface roughness, and corrosion resistance can also play a role in the overall performance of the plated roller.
