Temperature Range of Heat Transfer Salt?
Molten Salt ( The sodium nitrate/potassium nitrate salt ) Can Operate generally is used from 545 to 1049°F (285 to 565°C)
Benefit of Heat Transfer Salt Generally, nitrate salts provide a balance of wide operating range, thermal stability, corrosion performance and cost.
Advantage of the nitrate salts is corrosion performance . Nitrate salts are compatible with stainless steels up to 1049°F (565°C) and even carbon steel if the operating temperature is kept below 752°F (400°C). This makes them advantageous to use with common materials of construction to keep costs low. It is not advised to use yellow metals such as copper or brass with molten salts because they are not as compatible as steel at higher temperatures.
