Stress corrosion cracking
Ethanol
The effect of water content (0.5%, 5%, and 10%V) in E85 blend and 0.5%V E10 blend on the stress corrosion cracking (SCC) susceptibility of X-52 carbon steel was investigated. Slow strain rate tests (SSRT) coupled with electrochemical noise measurements (EN) were carried out using a strain rate of 1 X 10-6s-1. In general, scanning electron microscopy (SEM) observations on fracture surfaces showed a ductile behavior. However, secondary cracking was only observed for specimens exposed to solution containing up to 5%V water. En show of a likely localized corrosion process occurring at low water concentrations, whereas for water content above 5%V, a uniform corrosion process seems more likely to occur.
