51316-7363-Suitability of High Alloyed Materials in Molten Salts at 600 °C

Due to the composition of heat transmission media and temperatures, service conditions in solar facilities are, in many cases, extreme in terms of corrosion. By electrochemical measurements and exposure tests, the suitability of two alloys - X8NiCrSi38-18() and NiCr25FeAlYB - in molten nitrate salt (60 % NaNO3/40 % KNO3) was characterized at 600 °C.

Within the last years the use of feasible alternative energy source has risen and is going to replace fossil fuel supply more and more. Nevertheless service conditions in solar facilities are due to the chemical composition of heat transmission media and temperatures in many cases extreme in terms of corrosion. Since the construction of power plants shall be economical with maximum life service materials selection based on preliminary material qualification is essential to guarantee a secure and reliable operation of those facilities.The materials selection depends on the operation temperature of a power plant respectively on the chemical composition of the used transmission fluid. In high corrosive environments Ni-based alloys are often used as all-round solution not only for the construction of corrosion resistant parts because of its good corrosion properties. But there might be limits for the use regarding their corrosion behavior with which this contribution deals.Within this publication the suitability of selected high alloyed materials (including one newly developed alloy) in molten nitrate salt (60%NaNO3/40%KNO3) obtained by electrochemical measurements and exposure tests will be presented.

Keywords: downloadable, localized corrosion, nickel based alloys, solar energy, renewables, electrochemical characterization, X8NiCrSi38-18, NiCr25FeAlYB
