Cobalt Alloy Washers

Cobalt Alloy Washers are specialized disc components used to distribute the load of a nut or bolt head, protect the material surface, and often serve as mechanical spacers in high-performance bolted joints. Manufactured from cobalt-based superalloys (such as Stellite or other high-temperature variants), these washers retain exceptional hardness, resistance to wear, galling, and dimensional stability at extremely high operating temperatures (exceeding $1500^\circ F$). Their inherent corrosion and oxidation resistance make them essential for critical assemblies in gas turbines, high-temperature valves, chemical processing equipment, and furnace structures. Zeron Fastners supplies these washers, including flat and spring types, to ensure the long-term integrity of extreme-service connections.
