14. Corrosion resistance of environmentally resistant chains and sprockets

Corrosion resistance varies considerably depending on the conditions of use. This table does not represent the degree of guarantee.

Use this table as a reference to confirm the corrosion resistance of the chain under actual operating conditions before deciding on specifications.

○: Sufficient corrosion resistance △: Corrosion resistance is possible depending on the conditions of use ×: No corrosion resistance -: Unknown
