The two methods used in this study to estimate the cost of corrosion to the United States are based on: (1) the cost
of corrosion control methods and services, and (2) corrosion costs of specific industry sectors. Past studies have
indicated that the second method is more likely to incorporate the majority of the major corrosion-related costs and
the first method is likely to miss the significant cost of corrosion management, the cost for direct services related to
the owner/operator, and the cost of loss of capital due to corrosion.
