Plating is one method used to protect the surface of hydraulic cylinder rods against abrasion. One method used in rod repair is hard chrome plating.
Through its Research and Development department, PT Andalan Fluid Sistem (AFS) develops an alternative rod coating called Andalanfluids Super Corrosion Protection, or AFS SCP, for corrosion protection requirements.
AFS SCP for Hydraulic Cylinder Rod Corrosion Protection
AFS SCP is developed to provide improved corrosion resistance compared with conventional hard chrome plating, as shown in the AFS comparison data below. This coating alternative is intended for hydraulic cylinders in marine applications, power plants, and other applications requiring enhanced rust protection.

AFS SCP provides 6 times the corrosion resistance.
Note: The comparison must be interpreted in the context of its test methods and conditions. Surface corrosion percentages do not directly indicate a service-life multiplier for the rod. Discuss the technical details of the comparison and coating suitability with the AFS team for your application.
