Corrosion of stainless steels in lead–bismuth eutectic up to 600 °C

Oxide layer stability in lead–bismuth at high temperature

“…This difference between the two austenitic steels was unexpected, since the only significant difference in composition is the presence of Mo in AISI 316L. Soler et al [9] found similar differences in the behaviour of the two austenitic steels, even with higher oxygen concentrations.…”

Temperature Dependence of Corrosion of Ferritic/Martensitic and Austenitic Steels in Liquid Lead-Bismuth Eutectic

“…The LBE with low oxygen concentration induces dissolution attack. 3,6,7) Figure 9 shows EDX analysis of the cross-section of F82H after the corrosion test at 600 C. Although the oxide film with 10 mm thickness forms at the surface, the spot-like layer penetrated by LBE, the internal oxide layer and large pores are observed. It was reported that the line of pores and dispersed pores were often found beneath the surface oxide film in 8%Cr ODS steel after corrosion tests in LBE at 500 to 650 C. 8) The line of pores and dispersed pores may be linked to migration of Fe atoms due to surface oxide formation or loss of Cr-carbides and Crsulfides.…”

“…[3][4][5][6][7][8][9][10] It is pointed out that corrosion mechanism in LBE changes from protective oxidation to dissolution above 500 C while it depends on oxygen concentration and types of steels. [4][5][6][7][8][9][10] However, there are unclear points to make a quantitative prediction about corrosion in LBE because the obtained experimental data are still insufficient and scattered. Phenomena such as oxidation, grain boundary corrosion/ internal oxidation, penetration of LBE and dissolution of elements occur in LBE corrosion.…”

Corrosion behavior of Al-alloying high Cr-ODS steels in lead–bismuth eutectic

“…Austenitic steels, for example, suffer from severe dissolution attack at over 500°C [1][2][3]. Ferritic and martensitic steels, on the other hand, form thick oxide scales in similar conditions, restricting them to lower-temperature applications [2,4,5].…”
