The room temperature creep behaviour of various grades of the pipeline steels including X-52, X-70, X-80 and X-100 has been studied. Room temperature creep deformation was found to he strongly dependent of loading histories prior to creep loading. Pre-cold work generally increases the amount of room temperature creep deformation. Cyclic loading prior to creep loading often induces a burst of strain after a period of incubation ranging from a few minutes to a few hours. Mechanisms related to room temperature creep deformation are also discussed.
