Ultrasonic fatigue test at cryogenic temperatures on SUS304L by cold rolling ratio for LNG carriers

•This study examined the effects of cold rolling ratio and cryogenic temperatures on the mechanical properties of a 1.5 mm SUS304L sheet.•Moreover, to identify the effect of cryogenic temperatures, very high cycle fatigue (VHCF) characteristics were obtained at −162 °C and −196 °C, using the ultrasonic fatigue tester.•The increase in the fatigue limit caused by to the cold rolling and cryogenic temperatures in the results of the UFT is similar to the tendency of increased tensile strength and dynamic elastic modulus.
