Rolled steels for building structure (SN steels) are expecting to be steels for support structures in nuclear power plants instead of rolled steels for general structure (SS steels). Comprehensive tensile properties for SN steels were compiled at room and high temperatures so that they can be incorporated into the JSME material code. The effect of temperature on the tensile properties was approximately similar in spite of the different origins, material type, or plate thickness.
