This paper reports on the study of the mechanical properties and thermal constants of structural stainless steel at elevated temperatures. Because of the elements contained, stainless steel intrinsically excels, compared to conventional structural steels for buildings, in strength at elevated temperatures. The results of the high temperature tensile tests and thermal constant tests conducted on various stainless steels (SUS304, 316, 304N2) and their welding materials were expressed in numerical values and a data base for designing was prepared. The study has obtained the following conclusions: (1) Stainless steel has a much higher strength at elevated temperatures compared to ordinary structural steels for buildings, (2) The thermal constants differ from those of ordinary structural steels for buildings and, therefore, care is required when fire resistant designs involving the use of stainless steel are made.
