  This work addresses the early stages ($\le$1000 h) of the dissolution
corrosion behavior of 316L and DIN 1.4970 austenitic stainless steels in
contact with oxygen-poor (C$_O$ < 10$^-$$^8$ mass%), static liquid lead-bismuth
eutectic (LBE) at 500{\deg}C for 600-1000 h. The objective of this study was to
determine the relative early-stage resistance of the uncoated steels to
dissolution corrosion and to assess the protectiveness of select candidate
coatings (Cr$_2$AlC, Al$_2$O$_3$, V$_2$Al$_x$C$_y$). The simultaneous exposure
of steels with intended differences in microstructure and thermomechanical
state showed the effects of steel grain size, density of annealing/deformation
twins, and secondary precipitates on the steel dissolution corrosion behavior.
The findings of this study provide recommendations on steel manufacturing with
the aim of using the steels to construct Gen-IV lead-cooled fast reactors.
