This book was released on 1964 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A program is in progress in which the physical properties of 316 stainless steel and 21/4 Cr-- 1 Mo steel are compared in dynamic sodium systems at 1200 deg F and 1100 deg F respectively. This report presents the results of the first test series in which the fatigue, tensile, creep and creep-torupture properties of Type 316 ss were compared in 1200 deg F sodium, air, and helium environments. The results of these tests revealed: (1) The stainless steel specimens to be used throughout the program were representative of an average Type 316 ss heat. (2) The high temperature (1200 deg F) fatigue life of 316 ss in helium is longer than in air. The fatigue life of 316 ss in 1200 deg F sodium is the same as in air at high cyclic strains but is the same as in 1200 deg F helium at the low cyclic strains. Short time exposure to 1200 deg F sodium prior to high cyclic strain tests did not appreciably effect the life in sodium and helium but shortened the life in air. (3) No significant differences in the creep-rupture properties of 316 ss were discernible in air, sodium, or helium at 1200 deg F. Specimens exposed for 4000 hours (unstressed) in 1200 deg F sodium also showed no significant change in creep-rupture properties. (4) The creep rates of 316 ss appear to be consistentiy higher in 1200 deg F helium and sodium compared to 1200 deg F air; however, the results show the stresses to produce a minimum creep rate of 1% in 10,000 hours in all three environments to be within a 15% spread. (5) Tensile properties showed no significant differences when tested in air or helium regardless of whether the specimens were exposed for 4000 hours to sodium or whether the exposed specimens were washed or unwashed prior to testing.

This book was released on 1964 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A research program is being conducted to determine the effects of high- temperature reactor-grade sodium and contaminants (O, C, N) on the tensile, creep, creep-to-rupture, and fatigue properties of Type 316 stainless steel and 2 1/4 Cr--1 Mo steel. Tests 1 (stainless steel in 1200 deg F lowoxygen sodium, air, and helium) and 2 (2 1/4 Cr--1 Mo steel in 1100 deg F low-oxygen sodium, air, and helium) were completed. Test 3 (stainless steel in 1200 deg F high- carbon sodium) was delayed. In Test 4 (2 1/4 Cr--1 Mo steel in 1100 deg F high- oxygen sodium), the creep rupture tests show a shorter life of both the original and exposed specimens in sodium with 300 ppm oxygen than with 30 ppm oxygen; the fatigue life was the same in sodium with 300 and 30 ppm oxygen; and the creep rate in sodium with 300 ppm oxygen was lower than with 30 ppm oxygen but still higher than in air or helium.

Book excerpt: The research program was initiated for the purpose of determining the effects of high temperature reactor grade sodium, and normally anticipated contaminants, upon Type 316 stainless steel and 21/4 Cr-- 1 Mo steel. For comparison, the physical properties of these same materials were to be determined in air and helium. The test temperatures selected were 1200 deg F for the austenitic and 1100 deg F for the ferritic. The contaminants to be intentionally introduced into the sodium after the reactor grade sodium tests were completed are oxygen, carbon, and nitrogen. The types of test selected for revealing any possible effects of the envr-ronments upon the materials were tensile, creep, creepto-rupture, and fatigue. Tests 1 and 2 were completed. The complexity of the Na--C--stainless steel system has delayed the specimen testing in Test 3 (type 316 stainless steel in 1200 deg F high-carbon sodium). The creep, creep- torupture, and fatigue tests in sodium were completed for Test 4 (21/4 Cr- 1 Mo steel in 1100 deg F high-oxygen sodium). The creep tests show a lower creep rate in high-oxygen sodium as compared with low-oxygen sodium, but the creep rate is still higher than in air or helium. The creep-torupture tests show a shorter life in high-oxygen sodium, while the fatigue tests show no difference in fatigue life. Preliminary results indicate faster decarburization of 21/4 Cr- 1 Mo steel in high-oxygen sodium. (D.L.C.).

Book excerpt: A research program is being conducted on the effects of air, helium, and sodium on the creep, creep-to-rupture, and fatigue properties of Type 316 stainless steel and 2 1/4 Cr1 Mo steel. The program is divided into eight tests according to contaminants (O, C, N) in the sodium; Tests 1 and 2 have been completed, and Tests 3 and 4 are in progress. A summary of the status of the program and the results to date is presented. (D.L.C.).

This book was released on 1963 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.).

Book excerpt: Results are of a prelimnary nature at this time, but the sodium and air stress-to-rupture tests with 316 stainless steel specimens show excellent agreement indicating no noticeable effect of sodium. The creep tests of 316 stainless steel specimens resulted in higher creep rates in sodium than in air, which may indicate the shape of the creep curve to be differert in sodium than in air. The fatigue tests are not complete but preliminary results indicate Type 318 stainless steel has a longer fatigue life in helium and sodium than in air, especially under lower cyciic strain. The Cr-Mo steel stress rupture results show a slight difference between the air and sodium tests with indications that sodium might be expected to shorten the stress rupture life of 21/4 Cr--1 Mo steel at these high temperatures. Higher creep rates were also experienced in sodium than in air, indicating the possibility of differert shaped creep curves in sodium than in air. The fatigue tests show no difference between sodium and helium tests but both show longer fatigue life than tests in air. (R.J.S.).

Book excerpt: A research program is being conducted on the effects of sodium and contaminants at 1200 and 1100 deg F on the mechanical properties of Type 316 stainless steel and 2 1/4 Cr-- 1 Mo carbon steel, as compared to air and helium. Tests 1 and 2 were completed, and the final creep rates for 316 stainless steel and carbon steel in sodium containing 30 ppm O/sub 2/ are plotted. The shakedown operation phase of Test 3 (stainless steel in high-carbon sodium) is in progress. The results of some fatigue and creeprupture runs in Test 4 (2 1/4 Cr--1 Mo carbon steel in highoxygen sodium) indicate about the same fatigue life as in low- oxygen sodium and helium, and a slightly shorter creep-rupture life.
