Evaluation of the Notch Influence on the Stress Corrosion Cracking Susceptibility of the API 5L X70 Steel in Ethanol

The increasing interest in renewable and cleaner fuels has stimulated ethanol production in the last decades. The most cost-effective solution to transport large volumes of it are pipelines. However, there is evidence that ethanol may cause stress corrosion cracking (SCC). This phenomenon can be assessed by slow strain rate tests (SSRT) using smooth and notched specimens. This work aimed to evaluate the API 5L X70 steel susceptibility to SCC in...
