摘要：

Slow strain rate tests have been performed on annealed type 316 (UNS S31600) stainless steel in 5 ppm chloride content water at temperatures from 100 to 300°C under various applied potentials. At high potentials, large transgranular stress corrosion cracks occurred. A lower potential range for cracking also existed in which short transgranular cracks formed during the tests. Such cracks were initiated by the fracture of the oxide layer on the specimens, but the cracks then propagated into the matrix. The potential ranges of cracking were different at different temperatures and wine separated by a noncracking range. The potentials at which cracking occurs are mapped as a function of temperature. The results are compared with data for sensitized austenitic stainless steels.
