This report presents the results of a series of exploratory tests carried out to evaluate the possibility of stress corrosion cracking in various grades of stainless steels at close-to-ambient temperatures. This study investigated stress corrosion cracking in stainless steel exposed to salt droplets containing chloride ions at 50 ℃ (122 ℉) and deliquescence relative humidity. The findings indicated that some stainless steel grades can develop stress corrosion cracking and other forms of localized corrosion, whereas others are capable of better withstanding the impact of such a corrosive environment.

Bridge owners, consultants, contractors, and technical experts interested in the use of stainless steel as concrete reinforcement for corrosion resistance will find the information in this report beneficial.
