Abstract Scope |
In German nuclear power plants AISI 347 steel is frequently used for pipe components. The transfer of results from fatigue tests to component service life is always accompanied by an uncertainty. Therefore, pipe components manufactured from a pipe originally intended for use in a nuclear power plant, were characterized using a setup which allows pressures up to 80 bar and temperature cycling between 20 and 300 °C. These investigations were supported by instrumented fatigue tests on conventional specimens from same pipe and bars of same material. During all types of tests various non destructive testing methods were applied, to understand which are suitable to indicate and separate damage mechanisms in metastable austenitic steels. It could be shown, that the testing strategy performed and measurement techniques applied allow reliable calculations of (remaining) fatigue life for AISI 347 steel. |
