The stress corrosion crack (SCC) growth tests at high stress intensity factor (K) region on sensitized Type 304 stainless steel were carried out in 288 °C pure water using 50.8 mm (2-inch) thick compact tension (2TCT) specimens. The purpose of this study is to clarify the crack growth rate at high K region taking into consideration of the specimen constraint condition. 2TCT specimens were machined from 80-mm heavy thickness plate made of Type 304 stainless steel and were subjected to a
sensitization heat treatment. The crack growth rate at about...
