In this research, the influences of temperature and exposure time on the corrosion rate by sulfidation of an AISI-316 stainless steel were evaluated. It was exposed to different temperatures and times, simulating the transfer line entering to an atmospheric distillation unit in the crude oil processing. The gravimetric and surface characterization results indicated the strong influence of temperature and exposure time on evolution around a thermodynamically stable morphology. The iron sulfide layers (FeS) formed as corrosion products on the surface of AISI-316 steel, which played a protective role, reducing the material deterioration due to they acted as a barrier to the corrosion from other corrosive species in the system. |
