HYDROGEN EMBRITTLEMENT
We require our platers and suppliers of plated fasteners to bake case hardened parts to appropriate industry specifications. However, this process does not guarantee that hydrogen embrittlement will not still be present after baking or that it will not occur at a later date while in service. Specialized testing or a substitute part may be required, depending on the application.
