Isothermal and thermomechanical low-cycle fatigue of the hot work steel X38CrMoV5-3. Stress-strain and fatigue data for material with and without overaging heat treatment

This data set contains stress-strain as well as fatigue data of the martensitic hot-work steel X38CrMoV5-3 which was investigated through isothermal and thermomechanical fatigue tests conducted in the temperature range from 20 to 650 °C with mechanical strain amplitudes ranging from 0.5 to 1 %. The material was hardened and tempered to a hardness of 54 HRC and partly subjected to various overaging heat treatments.
