NACE International’s IMPACT Study Breaks New Ground in Corrosion Management Research and Practice

In 2002 the US Federal Highway Administration (FHWA) released a benchmark study, Corrosion Costs and Preventive Strategies in the United States (Koch et al. 2002), on costs associated with metallic corrosion in a wide range of industries. It revealed that the total annual estimated direct cost of corrosion was $276 billion, equivalent to 3.1 percent of the US gross domestic product (GDP). In addition to detailed cost analyses, the report presented preventive corrosion control strategies. The study, updated to account for inflation, is still widely used, but there had been no attempt at a more in-depth look at the effects of corrosion as related to corrosion management practices, particularly on a global basis. In October 2014 NACE International, the technical society for corrosion professionals with more than 36,000 members worldwide, initiated the International Measures of Prevention, Application, and Economics of Corrosion Technologies (IMPACT) study. The results were released in March 2016 at the NACE annual conference, CORROSION 2016, in Vancouver, and the report (Koch et al. 2016) is available at This article provides a summary of the scope, approach, and significant findings of the IMPACT study, including corrosion control strategies that could save hundreds of billions of dollars per year.
