Raybestos Powertrain Kolene® steel clutch plates are high quality engineered high performance products. Kolene® is a salt bath nitriding process. In generic terms, it is a thermochemical diffusion process, whereby ferrous parts are processed in molten salt with a specific nitrogen potential. In plain English, it provides a surface treatment that enhances wear and fatigue resistance from 200% to 500%. Kolene® plates are higher heat resistant and offer increased lubricity. Kolene® is a registered trademark of the Kolene Corporation.
