Suitability of high alloyed materials in molten salts at 600 °C
- Within the last years the use of feasible alternative energy sources has risen and is going to replace fossil resources 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 on the chemical composition of the transmission fluid used. In high corrosive environments Ni-based alloys are often used as an all-round solution for the construction of corrosion resistant parts, because of their good corrosion properties. However, there might be limits for their use regarding their corrosion behavior, with which this contribution deals.

By means of electrochemical measurements and exposure tests the suitability of two high alloyed materials X8NiCrSi38 18 and NiCr25FeAlYB in molten nitrate salt (60 % NaNO3/40 % KNO3) was characterized at 600 °C.…
