The objective of this work is to characterize the severity and key dependencies of the stress corrosion crack growth rate (SCCGR) in cold worked 304 stainless steel focusing on conditions where non-Arrhenius growth is observed. Testing was performed on five heats of 304 and 304/304L stainless steel in hydrogenated water at temperatures ranging from 204°C to 367°C, stress intensities from 14-82 MPa√m and cold work levels from 5-20%. Over 40 individual tests were performed on 97 samples, generating 402 additional measurements. Crack growth rates were monitored with in-situ direct current electric potential drop (EPD) and corrected by destructive exam. Results show that non-Arrhenius growth is typically observed above 310°C, where the growth rates plateau and then decrease at higher temperatures. The level of cold work and applied stress intensity can shift this peak to lower temperatures where a lack of temperature dependence has been observed in temperatures as low as 250°C in some cases. An empirical model has been developed to capture the non-Arrhenius dependence in SCCGR.
