Abstract

The first report on the cost of corrosion in Japan had been published at 1977. The report estimated that the corrosion loss in Japan which did not include indirect loss was 1-2 percent of Gross National Product (GNP) at that time. Since then, almost two decades have been passed and the industrial structure has drastically changed. Corresponding to this situation, the committee on the cost of corrosion in Japan was organized at 1999 jointly by Japan Society of Corrosion Engineering (JSCE) and Japan Association of Corrosion Control (JACC). The project was funded by the National Research Institute for Metals (NRIM) in the program of the Ultra-Steels (STX-21) Project. Cost of corrosion at 1997 was estimated by the Uhlig method and the Hoar method. The estimated cost was compared with the past data which was estimated at 1974 by the same Uhlig and Hoar method. In addition to the above estimation, the preliminary analysis by the Input/Output method is performed for estimating the total cost of corrosion including the direct and indirect cost. The overall cost estimated by the Uhlig and Hoar method at 1997 was found to be 3, 938 billion yen and 5, 258 billion yen, respectively, which is equivalent to 0.77% and 1.02% to GNP of Japan. The total cost including the direct and indirect cost, which is estimated preliminary by the Input/Output analysis, is likely to be more than 2 times larger than the direct cost estimated by the Uhlig method.
