Many alloys are available to designers for seal ring applications in aircraft and industrial gas turbines. In this paper, the capabilities of a number of alloys are reviewed. Emphasis is placed on thermal expansion, density, environmental resistance, high-temperature strength, microstructural stability after exposure to elevated temperatures, weldability, and brazability. Among the alloys considered, the Ni-Cr-Mo HASTELLOY® alloy S offers a potentially useful combination of properties for seal ring applications.
