Abstract
A method and device for reducing sulfidation corrosion and depositional fouling in heat transfer components within a refining or petrochemical facility is disclosed. The heat transfer components are formed from a corrosion and fouling resistant steel composition containing a Cr-enriched layer and having a surface roughness of less than 40 micro inches (1.1 μm).
