Performing Stress Corrosion Cracking (SCC) testing, analysis and mitigation – ensuring 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.
