Description

The influence of dissolved oxygen, hydrogen, and various impurity anions on the stress corrosion cracking (SCC) susceptibility of sensitized Type 304 stainless steel (SS) and alternative piping materials such as Types 316NG and 347NG SS is being investigated in constant-extension-rate-tensile (CERT) tests and in cyclic loading experiments on fatigue precracked fracture-mechanics-type specimens at 289/sup 0/C. In these experiments, the crack growth behavior of the materials is being correlated with the impurity concentration and the electrochemical potentials of Type 304 SS and platinum electrodes in simulated BWR normal operating environments (approx. 200 to 300 ppb oxygen and < 100 ppb of … continued below
