For equipment operated in extreme weather regions such as Eastern Europe, Northern Russia, and Canada, etc. (with average temperature is colder than –20°C during winter), measures against freezing are necessary for the materials that compose plant modules and metal materials for the components of automobiles. However, only a portion of research on the effects at high temperatures have been performed in the cases of high-speed tension tests for cryogenic materials until now with the effects at low temperature being confirmed only to the extent of the presence of differences at high and low speeds. In this study, characteristics of two universal materials for stainless steel, namely TP304 and TP316, at low temperature were examined by executing comparative tests on their mechanical characteristics at both ordinary temperature and low temperature. As a result, TP304 displayed a secondary stiffening phenomenon in the low temperature range. Meanwhile, TP316 displayed a reduction in the elongation ratio in the low temperature and it was confirmed that the maximum tensile strength increased more so than at ordinary temperature. Regarding temperature dependency, the maximum tensile strength and elongation ratio were higher for TP304, while the yield strength was higher for TP316.
