Chloride Induced Stress Corrosion Cracking (CISCC) is, arguably, one of the most prominent causes of failure of stainless steel structures. It is a well known fact that some coatings can leach significant amounts of chloride which can lead to a “micro-environment”, between the underlying substrate and the coating, promoting such corrosion. This has become such an issue over recent years that end users are now beginning to specify low amounts (typically <30ppm) of free chloride in the coatings to be applied to stainless steel.

This paper details the development of a method that clearly identifies a reproducible level of leachable chloride present in coatings.
