The stress corrosion cracking (SCC) susceptibility of carbon steel in fuel grade ethanol varies as a function of major and minor constituents in ethanol. The results of a round-robin testing on six different ethanol batches are presented. Significant variations in test results between the laboratories may result from apparently minor differences in test procedures. The variation in SCC susceptibility of different ethanol chemistries appear to be small.
