14. Corrosion Resistance Guide for CorrosionResistant Chains and Sprockets

Corrosion resistance varies accordingly depending on application conditions. This table should not be considered as a guarantee.

Using this chart as a reference, be sure to check the corrosion resistance of the chain in advance according to the actual operating conditions determining chain type.

○: Sufficient corrosion resistance △: Corrosion resistance in some applications ×: No corrosion resistance -: Unknown
