In this study, an attempt was made to assess changes in the microstructure of centrifugally cast tubes from GX40CrNiSiNb24-24 steel after a long-term operation under the conditions of a catalytic conversion of methane with steam. Changes in phase morphology occurring as a result of high temperature were identified.
