Strain-life data for type 316 austenitic stainless steels at temperatures between -269 and 816 degrees C (-452 and 1501 degrees F).
Abstract:ESDU 05007 presents strain-life data for type 316 austenitic stainless steels, including the low carbon and high nitrogen variants. The results of more than 300 tests performed at temperatures between -269 and 816°C (-452 and 1501°F) and at strain rates between 0.01 x 10-3 and 6.7 x 10-3 s-1 are given. The data are presented as plots of total, plastic and elastic strain amplitude versus the number of cycles to failure; the plots are accompanied by tables giving supplementary information regarding the material and test conditions. The data are discussed in detail and the results of a multiple linear regression analysis of the data are presented, culminating in an expression for predicted fatigue life as a function of total strain amplitude, temperature, strain rate and carbon and nitrogen content. A summary of the introduction to low-cycle fatigue phenomena presented in ESDU 04022 is given; this includes the derivation of the strain-life relationship and a discussion of the approximation of fatigue properties using monotonic data. A worked example illustrating the use of the data and of the expression resulting from the regression analysis is included. The effect on measured fatigue life of using alternative failure criteria is discussed in an appendix to the Data Item.
