We perform Stress Corrosion Cracking (SCC) mitigation to ensure structural integrity of components.
Stress Corrosion Cracking typically occurs due to improper materials selection, heat treatment and unforeseen environmental conditions, i.e., inadequate maintenance, thermal transient conditions, or lack of consideration of residual stresses. It is one of the most common environmentally assisted failure modes encountered. Read more about SCC.

President Bill O’Donnell, Sr. has published numerous Technical Publications which include topics in Stress Corrosion Cracking. A few are:
- Pressure Vessels
- Heat Exchangers
In considering the stress corrosion cracking problem in the heat affected zone of field welds in nuclear BWR primary pumping, the O’Donnell team developed a reliable mechanical stress improvement process which applies compressive stresses and is easy to control and verify.
