In March 2002, CC Technologies, now DNV Columbus, in conjunction with the FHWA and NACE International completed a two-year nationwide study for Congress showing a $276 billion per year cost of corrosion to the United States.
Cost of Corrosion by Industry
In the study, the financial impact to the U.S. economy for specific industrial sectors was determined and extrapolated to an estimated 3.1% of the gross domestic product. To learn more about the cost of corrosion to different industrial sectors, click on the links below:
Corrosion Control Methods
There are many corrosion control methods including protective coatings, corrosion resistant alloys, corrosion inhibitors, polymers, and anodic and cathodic protection. Corrosion control serivces, research and development, education and training can also help.
Protective Coatings
Both organic and metallic coatings are used to provide protection against corrosion of metallic substrates.
Metals & Alloys
Corrosion-resistant alloys are used where corrosive conditions prohibit the use of carbon steels and protective coatings provide insufficient protection or are economically not feasible.
Corrosion Inhibitors
A corrosion inhibitor may be defined, in general terms as a substance which, when added in a small concentration to an environment, effectively reduces the corrosion rate of a metal exposed to that environment.
Plastics & Polymers
In 1996, the plastics industry accounted for $274.5 billion in shipments. It is difficult to estimate the fraction of plastics used for corrosion control because in many cases plastics and composites are used for a combination of reasons.
Cathodic & Anodic Protection
The cost of cathodic and anodic protection of metallic structures subject to corrosion can be divided into the cost of materials and the cost of installaion and operation.
Research & Development
Over the past few decades less funding has been made available for corrosion-related research and development, which is significant in light of the costs of maintaining aging infrastructure.
Corrosion Control Services
In the context of this report, services are defined as companies, organizations and individuals that provide contract services for corrosion control purposes, while excluding corrosion-related activities that owners/operators may do in-house.
Education & Training
Corrosion-related education and training in the United States includes degree programs, certification programs, company in-house training, and general education and training.
