    초록 A steam generators are shell-and-tube heat exchangers consisting of several to tens of thousands of tubes. The failure of a steam generator tube brings economic loss from decreasing efficiency and makes it difficult to ensure the safety of a nuclear plant, so the investigation of fracture characteristics is essentially needed. It is known that the hoop stress is the main fracture reason of the SGT. However, in the fracture analysis of a SGT, the longitudinal tensile properties of a SGT or even original material has been used instead of hoop tensile properties, because a SGT is thin and has too small diameter to be manufactured into the standard tensile specimen in hoop direction. In this study, both ring tensile test which can measure the hoop tensile properties from a small tube and longitudinal tensile test were conducted. As a result, we obtained the tensile properties of a SGT.
