Abstract

This report concerns the evaluation of high cycle fatigue properties of three austenitic stainless steels: type AISI 316 (UKAEA tests), type AISI 316L (CEA tests) and type AISI 304 (Interatom tests). The testing conditions chosen by the three partners had not been harmonised prior to the test. Experimental procedures and statistical treatments used for the three subsets of data are described and discussed. The HCF properties of the three steels were found to be consistent with the 0.2% proof stress, the fatigue limit being larger than the latter at temperatures above 550 C. The type 304 steel had lower tensile properties than the two other steels and hence also lower HCF properties. Parameters which have a significant effect on HCF behaviour are mean stress or R-ratio (less in the non-endurance region than in the endurance region), temperature, cast or product.
