One of them is intended for Liquefied natural gas (LNG) tank applications. During the transport voyage, this storage tank is maintained at a temperature range of -160 at atmospheric pressure. This material is specific because it has advantages including high strength, excellent corrosion resistance, and excellent welding performance. This study presents an impact test to evaluate the toughness of 304 stainless steel under cryogenic temperatures. The test was carried out by testing Charpy V-notch specimens which were carried out at room and cryogenic temperatures. Prior to testing, the specimens were immersed in liquid nitrogen for at least 10 minutes. The absorbed energy is captured in the experiment and plotted against the high temperature. After testing, metallographic observations were made to observe crack patterns at normal temperature and cryogenic temperature. The results show that a clear transition toughness behavior from ductile to brittle transition cannot be identified for SUS 304 material. © 2024 The Authors. Published by ELSEVIER B.V.
