Intergranular stress corrosion cracking (IGSCC) of Type 304 stainless steel has occurred in various piping systems of Boiling Water Reactors (BWR) after a number of years of service. The cracks were associated with the heat affected zone (HAZ) of welds and were detected as slight through wall leaks. The number of cracks has been small in comparison to the total number of welds. By 1975, 64 out of approximately 16,000 available welds had developed penetrations. Since then several studies were initiated to establish the cause of the pipe cracking and provide approaches for corrective action.
