Representative Clients

In 2001, NACE published a report titled, “Corrosion Cost and Preventative Strategies in the United States.”  They found that the total direct cost of corrosion is estimated at $276 billion per year.  This cost was determined by analyzing 26 industrial sectors in which corrosion is known to exist, and extrapolating the results for a nationwide estimate.  In addition, large indirect corrosion costs include lost time and lost productivity because of outages, delays, failures, and litigation.  Within the total cost of corrosion, a total of $121 billion per year is spent on corrosion control methods and services.

Working in both the consulting and litigation-support arenas, Exponent assists clients in a diverse range of industries, including:

  • Pipeline Industry
  • Power Generation
  • Nuclear
  • Mining
  • Marine
  • Construction
  • Biomedical
  • Manufacturing
  • Chemical Processing
  • Pulp and Paper
  • Infrastructure
  • Fire Protection
  • Utilities
  • Electronics
  • Transportation
Laboratory Facilities

Exponent's laboratory facilities related to corrosion testing and evaluation include potentiostats, galvanostats, zero-resistance ammeters, electrochemical cells, metallographic equipment, optical and scanning electron microscopes, energy dispersive spectroscopy, and tensile test equipment.
