Stress Corrosion Cracking (SCC) typically occurs due to improper materials selection or heat treatment, design issues, 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.
O’Donnell Consulting evaluates stress corrosion cracking (SCC) and develops solutions to mitigate its effects. In addition, we perform Fitness-For-Service evaluations per API-579 and ASME Section II – as well as evaluating NDE test results and designing weld repairs.
Call us to assist you resolve your SCC issues – enabling you to lower costs, and improve safety.

President Bill O’Donnell, Sr. has published numerous Technical Publications which include topics in SCC. A few are:
- Pressure Vessels
- Heat Exchangers
In considering the stress corrosion cracking problem in the heat affected zone of field welds in 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.
