The importance of corrosion testing

Without corrosion tests, we would expect many more failures to occur. That is the importance of corrosion testing.

Corrosion Testing by ASTM B117 Salt Fog Test

As society advances, we are continually pushing technologies to their limits. This applies to materials and metals just as well as to computers, and it means that safety is always being challenged by improvement. To meet this challenge, a wide range of corrosion tests have been created to evaluate materials performance in the simulated or real environment. Many of these tests involve simulated analyses in a laboratory to reduce or eliminate the impacts of corrosion.

We perform many different corrosion tests with goals such as: (1) determining the rate of corrosion over time – for example ASTM G31, (2) evaluating for susceptible materials such as ASTM A262, (3) analyzing the effect of hydrogen on material, and (4) assessing in-field corrosion testing. These tests often provide the critical last line of protection that prevents unacceptable materials from being used.

 

We welcome your input and comments: How have you seen corrosion testing make an impact in the world?

 

The cost of corrosion exceeded $1 trillion in United States in 2013

 

Cost of Corrosion Estimate for 2013 by G2MT Labs

Cost of Corrosion Estimate for 2013 by G2MT Labs

The infographic above illustrates the growth in corrosion costs and shows how large of a draw on our economy corrosion is. With little fanfare, a significant milestone in the effect of corrosion on the U.S. economy occurred in 2013 when the total cost of corrosion in the US exceeds $1 trillion annually for the first time. In a widely-cited study (NACE Corrosion Costs Study) by the National Association of Corrosion Engineers, NACE, the direct cost of corrosion in the U.S. was estimated to equal $276 Billion in 1998, approximately 3.1 % of GDP. However, this estimate is incomplete and outdated.

Closer examination of the 1998 NACE corrosion study’s own analysis, along with a calculation of inflation since the report was produced,  indicates that total corrosion costs in the U.S. now exceed $1 trillion dollars a year, and probably exceeds $5 trillion annually around the world (assuming 6% of the GWP of 84.97 Trillion in 2012) . The indirect cost of corrosion of is estimated to be at least equal to the direct cost. In that case, the total cost of corrosion is $993 B in March 2013 and estimated to exceed $1 trillion June 2013 (based on estimates of GDP from http://forecasts.org/gdp.htm).
