AUSTENITE STEEL, LEAD MELT, CORROSIVE DAMAGE, STRUCTURE
The peculiarities of corrosion behavior of austenitic X18H10T steel in lead melts with oxygen concentration C [O] Pb ≈ 5 ∙ 10-7 wt.% At 550 ° C at 250, 500 and 1000 h exposures were evaluated. It is established that the corrosion damages of the surface layers are inter-crystalline in nature, which is accompanied by the etching of the grain boundaries and the penetration of the melt into the matrix while dissolving the basic alloying elements Ni, Cr, Mn in lead. The kinetics of the growth of the damaged surface layer is shown, depending on the duration of the exposure on the basis up to 1000 h.
