Abstract : Characteristics of sulphide corrosion products in K18 carbon steel after 11 years of service in a low-sulphur refinery furnace environment have been examined in order to better understand the mechanism of sulphur-related damage to the steel. Optical microscope and scanning/transmission electron microscopes techniques have been involved in the study. Four types of the corrosion products of different morphology and origin have been presented: (1) iron sulphide scale on the steel surface, (2) sulphur-rich particles at ferrite grain boundaries, (3) degraded sulphur-enriched cementite particles at other ferrite grain boundaries and similar particles within pear-lite grains, and (4) irregular iron sulphide inclusions in the subsurface metal layer that were not-related to the boundaries of the grains.
