Stress Corrosion Cracking Mitigation
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 ocurrs due to improper materials selection or heat treatment, design issues, and unforseen environmental conditions, i.e., inadequate maintenance, thermal transient conditions, or lack of consideration of residual stresses.

Optimal Consulting evaluates stress corrosion cracking and performs Fitness-For-Service evaluations per API-579 and ASME Section II. We evaluate NDE test results, design weld repairs, and design safety constraints. We have proprietary SCC mitigation technology which has been successfully used in numerous applications.
