Corrosion behavior of CLAM steel in static and flowing LiPb at 480°C and 550°C

Compatibility of CLAM steel weldments with static LiPb alloy at 550°C

“…For example, the DRAGON-I is made of 316SS and the suggested working temperature is 500 • C, while DRAGON-II is made of Inconel working at 700 • C. DRAGON-III which is under construction, will be made of SiCf/SiC and operate at 1000 • C. Ref. [21] discussed the effect on corrosion of different materials such as 304 stainless steels, Fe-Cr steel and pure molybdenum. The results show that the effect of these materials on corrosion is mainly due to the isothermal mass transfer between dissimilar metals during the corrosion process.…”

Long-term corrosion behavior of martensitic steel welds in static molten Pb–17Li alloy at 550°C

“…According to Ref. [13], Cr could be more readily depleted in the initial stages of the corrosion. The rate of Cr depletion is greater than that of Fe within the first 1000 h. After 1000 h the rate of Cr depletion decreases while that of Fe remains constant or slightly increases.…”

“…In China, the FDS team conducted series of experiments on the corrosion behavior of CLAM steel. CLAM steel showed similar overall corrosion behavior to the other RAFM steels in liquid Pb-17Li and the main corrosive attack is via dissolution of the steel matrix components after some incubation period [11][12][13]. The chemical compositions of CLAM and other main RAFM steels are shown in Table 1 [14], all of them are 9Cr based martensitic steel.…”

Effects of Yttrium on Microstructure Stability and Tensile Properties of China Low Activation Martensitic Steel

“…CLAM, 9Cr-1.5W-0.2V-0.15Ta, was developed by the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP), and other institutes and universities [8]. The smelting process [9], mechanical properties [10], compatibility with liquid LiPb [11], and further research and development [12] of CLAM have been evaluated by the ASIPP.…”
