 Problem statement. The development and implementation of low-carbon low-alloy steels of high strength in the structural elements of blast furnaces, which will operate in conditions of heating to high temperatures is an urgent problem and can give a significant effect during the operation of buildings and structures.. Purpose of the article. establishing changes in the structural state of low-carbon low-alloy steels depending on the temperature rise. Conclusion. Conventionally, the temperatures at which the studied steels can be operated can be divided into two levels: the temperature below which no significant structural changes are detected; temperature at which significant structural changes are observed, which lead to a decrease in the reliability of structures. The presence of two levels associated with both the development of diffusion processes and the ability of the structural state to resist the effects of temperature stresses (structural stability). The structural stability of steel with increasing temperature is due to the processes that bring the system closer to the position of thermodynamic equilibrium compared to low temperature (structural state at room temperature), which is usually optimal in terms of performance. Such changes include the processes of recrystallization, coagulation of secretions and other phase transformations that lead to changes in the macro- and microstructure that impair the performance properties of the material. At relatively high temperatures, these processes occur at a significant rate, as a result of which they are crucial in limiting the possibility of using this material.

Abstract EASTERN STAINLESS TYPE 310S has high resistance to corrosion and oxidation at high temperatures. It also has high strength at elevated temperatures. Thus it is especially suitable for service at high temperatures. It is very ductile and can be welded readily. Among the many applications for Type 310S, a few typical uses include annealing boxes, chemical plant equipment, fire box sheets, furnace linings, heat exchangers, oil-refining equipment, kiln linings and tube hangers. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-450.

With the wide application of high strength concrete in the building construction,the risk making concrete subject to high temperatures during a fire is increasing. Comparison tests on the mechanical properties of high strength concrete (HSC) and normal strength concrete (NSC) after the action of high temperature were made in this article, which were compared from the following aspects: the peak stress, the peak strain, elasticity modulus, and stress-strain curve after high temperature. Results show that the laws of the mechanical properties of HSC and NSC changing with the temperature are the same. With the increase of heating temperature, the peak stress and elasticity modulus decreases, while the peak strain grows rapidly. HSC shows greater brittleness and worse fire-resistant performance than NSC, and destroys suddenly. The research and evaluation on the fire-resistant performance of HSC should be strengthened during the structural design and construction on the HSC buildings.
