EFFECT OF 1200 F SODIUM ON AUSTENITIC AND FERRITIC STEELS. Bi-monthly Progress Report No. 1 for July and August 1959 on THERMAL SHOCK, NITRIDING, STRESSED CORROSION, UNSTRESSED CORROSION

Completion of preliminary designs for a thermal shock loop, a corrosion loop, and a nitriding loop is reported. Stressed and unstressed corrosion studies are scheduled to be carried out in the same system. A literature search was started, and various sites were contacted to avoid daplication of effort. It was found that some work has been done at 1200 deg F sodium temperature with various oxygen concentrations, however part of the data is contradictory. Test plans include corrosion testing of Croloy and stainless steel samples as well as similar and dissimilar welds of these materials in 1200 deg F sodium. (J.R.D.)
