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 simulated fuel-grade ethanol (SFGE) through SSRT and to investigate the influence of the specimen geometry on the results produced. Indeed, the standard NACE TM 0111 describes the geometry for two types of specimens, i.e., notched and unnotched, and for the former even defines the notch characteristics. The results have shown that the API 5L X70 steel is susceptible to SCC when exposed to ethanol and that the use of notched specimens turns this susceptibility more evident.
