The creep deformation behaviour of two heats of nuclear grade type 316 stainless steel has been studied at 823 Κ at stress levels of 216, 245, 275 and 294 MPa, with test durations exceeding 84000 hours. Normal creep behaviour was observed at all stress levels except at 216 MPa. The creep deformation behaviour at 216 MPa was characterised by renewed primary and secondary creep stages for both heats of material. This anomalous behaviour is found to depend on carbon content and grain size of the material.
