Fossil fuel and nuclear power generation plants require extensive use of heat exchangers, many of which require corrosion resistant alloys to handle low quality cooling water. Clad steel is extensively for heat exchanger tubesheets. The largest clad tube sheets are used in the final low pressure condensers. For most coastal and brackish water cooled plants, titanium is the metal of choice technically, and titanium-clad tubesheets are the low cost solution for power plant condensers. Clad metal use in various types of electrical power generation techniques is focused on a few specific applications. Unlike the chemical process industry and oil refining industry, clad metal use in the power industry has had a history of targeted uses.
