Corrosion tests for evaluation of corrosion resistance of domestic oxide dispersion strengthened ferritic steels

Yutani, Toshiaki*; not registered; not registered

Corrosion tests with tellurium and iodine were conducted at 500, 600 and 700 $^{circ}$ C for 100 hours, to evaluate corrosion resistance to fission products. Domestic oxide dispersion strengthened ferritic steel tubes (13Cr-0.5Y $_{2}$ O $_{3}$ -0.5Ti-3W steel and 11Cr-0.25Y $_{2}$ O $_{3}$ -0.5Ti-2W steel), high strengthened ferritic/martensitic steel tube (1FK) and modified SUS316 stainless steel tube were tested. The results were summarized as follows. (1)13Cr-0.5Y $_{2}$ O $_{3}$ -0.5Ti-3W steel was superior to and 11Cr-0.25Y $_{2}$ O $_{3}$ -0.5Ti-2W steel and 1FK were inferior to the modified SUS316 stainless steel in corrosion resistance to tellurium at 700 $^{circ}$ C. (2)It was recognized that corrosion resistance to tellurium improved with chromium content at 500 and 600 $^{circ}$ C. (3)All steel specimens had the highest weight losses at 600 $^{circ}$ C in the corrosion tests by iodine. (4)13Cr-0.5Y $_{2}$ 0 $_{3}$ -0.5Ti-3W steel, 11Cr-0.25Y $_{2}$ O $_{3}$ -0.5Ti-2W steel and 1FK were inferior to the modified SUS316 stainless steel in corrosion resistance to iodine at 600 $^{circ}$ C.
