Corrugated 304L stainless sheet steels are adopted as a membrane panel of liquefied natural gas (LNG) containment system in order to withstand frequent changes in the thermal conditions during operation. 304L stainless steel is transformation induced plasticity (TRIP) steel that exhibits nonlinear material behavior, because it undergoes phase transformation during plastic deformation. Since the TRIP behavior is a very important mechanical characteristic in a low-temperature environment, significant amounts of data are available in the literature. However, quantitative data on the effect of pre-straining on low-temperature mechanical behavior of stainless steel is not available, although corrugated sheets are subjected to significant amounts of pre-strain during operation. In this study, tensile tests on pre-strained 304L stainless steel have been carried out in a cryogenic environment in order to analyze the effect of pre-straining on the strength and ductility of the material. The strain hardening rate of 304L stainless steel at low temperatures, which is the most important characteristic, is also quantitatively evaluated.
