The corrosion behavior of several Fe-Ni-Cr alloys in static liquid lithium are reported in this paper. The alloys were 316SS, Ti-modified 316SS, HR-1, low activity HT-9, HT-9 and HT-7 steels. After exposure in lithium at 500°C for 963, 1295, 1707, 2115 and 2495 hours the weight changes of the corroded specimens were analyzed using a scanning electron microscope and electron probe. The results showed that big differences exist between the auste-nitic stainless steels and the ferritic steels. Besides, the effects of nitrogen content on the lithium corrosion behavior of the alloys are also given.
