EFFECT OF 1200 F SODIUM ON AUSTENITIC AND FERRITIC STEELS. PHYSICAL PROPERTIES OF MATERIALS. Progress Report 36, August 1963
A research program is being conducted on the effects of reactor grade sodium and contaminants in sodium on Type 316 stainless steel and 2 1/4 Cr- 1 Mo steel. Tensile, creep, stress-to-rupture, and fatigue tests were carried out on specimens in sodium, helium, and air. The results for 318 stainless steel indicate a lower stress for a creep rate of these for 2 1/4 Cr-- 1 Mo steel indicate a lower stress in 1100 deg F sodium and a higher stress in helium than in air for the same creep rate. Higher oxygen contents (300 ppm) in 1100 deg F sodium led to shorter rupture times in stress-torupture tests on 2 1/4 Cr-- 1 Mo steel, but the difference decreases with stress. Creep tests indicate lower creep rates for higher oxygen contents in sodium. (D.L.C.)
