A series of slow strain rate experiments have been performed in order to determine the influence of 60 weight percent NaNo{sub 3}-40 weight percent KNO{sub 3} salt environment on the tensile properties of several Fe based containment alloys. The results of these tests indicated that at 600 C high Cr austenitic stainless steels suffered no measurable degradation in their mechanical properties (tensile strength and ductility) when compared to air exposed control specimens. Lower alloy steels such as 2.25 Cr - 1 Mo did, however, suffer a significant loss in ductility when exposed to this environment at 450 and 525 C. Alloy strength was also markedly affected as the result of salt exposure. These results along with the influence of deformation on the structure of the oxide films formed in the salt environment are discussed.
