AB  - Centrifugally cast reformer tubes are used in petrochemical plants forhydrogen production. Due to the conditions of hydrogen production, reformertubes are exposed to high temperature which causes creep damage inside themicrostructure. In this study, two different ex-service HP40 alloy reformertubes which come from the same steam reformer unit have been compared bymicrostructural characterisation performed at a range of length scales from mmto um. Analyses performed by EBSD (Electron Backscatter Diffraction), EDS(Energy Dispersive X-ray Spectroscopy) and PCA (Principal Component Analysis)show that both tubes have similar microstructural constituents, with thepresence of an austenitic matrix and M23C6, G phase and M6C carbides at thegrain boundaries. Even if both tubes have a similar microstructure, one tubedue to it localisation inside the steam reformer unit presents a region withmore micro cracks which may indicate that this tube have accumulated more creepdamage than the other one.
