Failures of structures often involve environmentally assisted cracking. Stress corrosion cracking (SCC) is one of the most common environmentally assisted failure modes encountered. It 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.
O’Donnell Consulting evaluates stress corrosion cracking (SCC) and performs Fitness-For-Service evaluations per API-579 and ASME Section II – as well as evaluating NDE test results and designing weld repairs. Let us help you resolve your SCC issues – enabling you to lower costs, and improve safety.

Bill O’Donnell, Sr. has published numerous Technical Publications which include topics in SCC. A few are:
“Mitigation of Stress Corrosion in Reactor Nozzles and Core Structures”
“Mechanical Methods of Improving Resistance to Stress Corrosion Cracking in BWR Piping Systems”
“New Mechanical and Thermal Processes to Mitigating Stress Corrosion and Corrosion Accelerated Fatigue”
A few examples include:
- Petrochemical
- Oil/Gas
- Process
- Energy
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.
