Tough against water and alkalis without strength reduction by a special surface treatment
NEPTUNE Chain is Surface-treated chain that uses a base RS Drive Chain with a special coating and top coating.
They have the same tensile strength and allowable load as RS Drive Chain thanks to using a special treatment process that does not affect chain strength and offers superb saltwater, weather, and chemical resistance.
Furthermore, they use no harmful chromium and conform to the RoHS Directive.
* NEPTUNE Chains have less corrosion resistance than stainless steel chain.
