Evaluating Stress Corrosion Cracking K_ISCC and (da)/(dt) in Hydrogen Sulfide Solutions with Instrumented Bolt WOL Specimens

Stress Corrosion threshold stress intensity K_ISCC and stress corrosion crack growth rate (da)/(dt) have been measured for 16Mn steel in H₂S aqueous environments with WOL specimens. In order to monitor crack growth in WOL specimens, a technique of instrumented bolt was used in this work. It is found that the technique of instrumented bolt provides several advantages, including enough accuracy and convenient operating.
