► Constant load test of corroded specimen is useful for evaluating delayed fracture. ► Delayed fracture is controlled by diffusible hydrogen concentration. ► Hydrogen entry is enhanced with progress of atmospheric corrosion. Constant load tests of circumferentially notched round bar specimens of hig...
