OSTI ID:10183207
In stainless steel equipment exposed to tritium, embrittlement is thought to involve interactions between internal He and the complex triaxial stress state that arises when necking starts. Recent efforts have been directed at determining He concentration thresholds for this effect in several austenitic stainless steels. This report describes results of tests on 304L stainless steel containing low He-3 contents. 304L ss containing 0.47 and 4.1 appM He-3 tested at 803--814{degrees}C had lower tensile properties than uncharged samples. Mechanical properties were not affected by 0.47 appM at 615{degrees}C but ductility was severely decreased at 810{degrees}C.
