Mechanical properties of stainless steel bolts at elevated temperatures

Conference Paper


Abstract


  • In order to promote fire resistance of bolts connections, this paper developed an experimental program for investigating mechanical properties of stainless bolts at elevated temperatures, in which standard coupon specimens were prepared and performed for two types of stainless bolts subjected to tensile loading. The research findings accomplished on fire resistant bolts have been reviewed carefully and compared with mechanical properties of stainless steel bolts in fire. In addition, stainless steels (EN 1.4401 and EN 1.4571) as their parent materials were included in this investigation. It can be found that strength and stiffness reduction of stainless bolt materials is almost in consistency with their parent materials in fire. A better performance in strength retention has been observed for these materials in the temperature range of 500 to 900°C, compared to fire resistant bolts. Relying on the experimental data, strength and stiffness reduction factors have been derived for stainless steel bolts for help with determination of their stress-strain relationships at elevated temperatures.
