Home > What We Do > Corrosion Testing Lab


Corrosion, in its myriad forms, costs industry and manufacturing in the neighborhood of $3.5 billion annually. The experts at IMR Test Labs can offer testing and consultation services to provide failure and root cause analysis to identify and mitigate costly field and plant failures.  Our corrosion testing experts can also offer insight on materials selection, designed to pre-empt corrosion effects on metal, plastic and composite components.  If you are looking for salt spray and other accelerated weathering, click here.

We can identify corrodents and other environmental variables that are directly responsible for corrosion attack.  We have a history of addressing complicated corrosion issues including stress corrosion cracking, microbial induced corrosion, environmental stress cracking, and many other mechanisms.

Whether it’s an exotic prosthetic material or petroleum storage tank, our broad array of analytical capabilities (SEM-EDS, Ion Chromatography, GC/MS, FTIR and more) and a talented team of experienced failure analysts who know what’s at stake, we are committed to preventing or solving your corrosion problem and providing you with the answers you need....on time! That is our commitment.

The IMR corrosion testing lab helps you estimate component service life, compare candidate materials in your service environment, and help screen your materials and their condition.

We now offer Slow Strain Rate testing to ASTM G129.  We can test all types of metallic materials in a wide range of liquids at temperatures from ambient to 100°C.  This test method is used to determine the susceptibility of materials to Stress Corrosion Cracking or Environmetally Assisted Cracking by simulating in-service mechanical stresses, aggressive environments and temepratures.  Contact Bill DeLaurier today to learn more about our capabilities, or to discuss your test plan.
