Low cycle fatigue - strain control test data for P91 material at 550 °C (specimen identifier P91-S7)

The data set contains strain controlled low cycle fatigue data with or without hold periods for austenitic stainless steel 316L and ferritic-martensitic steel P91. The total strain range for tests is from 0.5% to 1.0% and the temperature range is from 823K to 873K. The hold period length is from 0 to 1800 sec. For 316L the hold period is applied both in tension and compression for all tests, whereas for P91 data set includes tests with hold period only in tension, only in compression and both.
