The corrosion of the 10X2M weldment made in Russia for outlet pipe of CEFR super-heater and the weldment of Russia 12X1 M with domestic 304HS.S.for inlet pipe were investigated in 495℃ thermal convection sodium for 2 800 hours.the oxygen concentration in sodium is≤25 μg/g,and carbon is 26 μg/g. The measurement and analysis for corrosion rate, micro-corrosion morphologies, element contents at surface of the weldments, the mechanical properties and the morphologies of the rupture surface were performed after test. The results showed that the compatibility of the two weldments with high temperature sodium is good under these test conditions.
