NUST MISIS and PAO Severstal Plan to Create Construction Steel with Better Fire Resistance

Scientists from the National Research Technological University NUST MISiS and Severstal, Metal-Expo regular exhibitors, are planning to create new fire resistant steels by forming non-Fire Resistant Steel.

Scientists from the National Research Technological University NUST MISiS and Severstal are planning to create new fire resistant steels by forming non-metallic inclusions at elevated temperatures. The use of new steels will slow down the collapse of steel structures in a fire under the influence of high temperatures, creating an additional margin of time for the evacuation of people.

As a result of fires, metal elements of buildings quickly lose their bearing capacity. This leads to the loss of the integrity of building structures and their severe deformation, in which it becomes impossible to carry out rescue operations and extinguish a fire. Buildings can be destroyed before the completion of the rescue operation, which leads to an increase in the number of victims, further requires significant costs for repair and restoration work and leads to large, in some cases almost irreparable environmental damage.

Thanks to the introduction of the development, the collapse of steel structures in a fire under the influence of high temperatures will occur later, creating an additional margin of time for the evacuation of people, the researchers believe. Their plans are to increase the resistance of steel structures in fire conditions by at least 15 minutes. This will increase the level of operational safety of industrial buildings, shopping centers, sports facilities and save the lives of many people.

The project is being implemented by NUST MISIS jointly with PJSC Severstal on a subsidy from the Government of the Russian Federation, provided for the development of cooperation for the creation of high-tech industries.
