Proposed Standard Test Method for Ethanol SCC of Steel

This paper describes a proposed standardized test method for evaluation of steels for susceptibility to stress corrosion cracking (SCC) in fuel grade ethanol (FGE) and other ethanolic environments and blends. It is based on work that was performed as part of the ethanol SCC program funded by American Petroleum Institute (API) and includes the use of a notched slow strain rate (N-SSR) test procedure. Additionally, this paper describes background data developed in this program and modified data analysis procedures to facilitate the use of this test method for evaluation of the influence of environmental and metallurgical variables.
