Stress corrosion crack growth rate measurements were performed on 308L stainless steel weld metal aged at 400 °C for 10000 hours. Tests were performed on a 0.5TCT specimen in BWR water at 288 °C monitored by DC potential drop as a function of corrosion potential water purity and stress intensity factor. SCC growth rates on the aged weld metal were similar to those measured on sensitized or 20% cold worked stainless steel.
