ehavior of high strength low-alloy (HSLA) steel at elevated temperatures

In this paper experimental data about the creep behavior of high strength low-alloy (HSLA, ASTM A618) steel are presented. For different elevated temperatures (Ti) tensile tests are carried out and also for some of the mentioned elevated temperatures one-dimensional creep tests for different constant loads (Fi) are made. Experiments are carried out using computer controlled 400 kN materials testing machine equipped by a high temperature furnace and a corresponding high temperature extensometer. These experiments belong to the testing material mechanical properties and viscoplastic responses of the material under consideration. The obtained results of material properties and creep behavior are necessary for determining e.g. the load-carrying capacity of a structure under fire conditions as well as for its lifetime prediction.
