Abstract
The fracture reason of circulatory pump bolts was analyzed by metallography examination, fracture analysis and chemical composition analysis. The results showed that the fractured bolts' material was not the design material, and failure of the bolts was due to the stress corrosion crack propagation of bolts' austenitic material by chloride ion in seawater.
