摘要：
Static corrosion tests for SS304 and SS316L austenitic steels in high purity LiF-BeF2 (Flibe) were carried out at 500 and 600 degrees C for 1000 h. After the exposure, the steel surfaces were corroded due to the fluoridation by HF dissolved in Flibe. The grain boundary of the steel surfaces was preferentially attacked. The mechanism of corrosion including selective intergranular attack was discussed. The corrosion rate of SS304 and SS316L in Flibe at 600 degrees C was estimated as 10.6 and 5.4 mu m/year, respectively. (c) 2009 Elsevier B.V. All rights reserved.
