The mechanism of corrosive degradation of the interior of a boiler steam drum was investigated. This involved analysis of the feedwater and boilerwater, phase and elemental analysis of the corrosion products, and microstructural observation after preparing replicas of the attacked regions. The operation of crevice attack was identified as the most detrimental mode of corrosion in the present case. The accelerating influence of chlorine on such deterioration is discussed. The chronological deposition of the corrosion products are explained by the mechanism of attack. The presence of various transition compounds in the corrosion product are due to the sequence of chemical events during crevice attack.
