Russia has developed a new type of steel

“The idea is to develop a new material that will be operable at elevated superheated steam temperatures, actually going to supercritical parameters. This will make it possible to significantly reduce the amount of fuel burned and, consequently, get a significant economic benefit as well. We’re talking about five million rubles per day per power plant,” said Roman Mishnev, one of the authors of the project.

In their developments, the researchers were guided by the basic commercial steel R92 and applied new alloying approaches, i.e. they actually changed the composition. For example, scientists added more boron and lowered the nitrogen content.

“This led to the fact that today the developed material has no analogues in terms of mechanical properties neither in Russia nor abroad. I’m talking primarily about creep resistance. The new steel is quite comparable in characteristics with much more expensive austenitic steels and superalloys like Inconel,” Mishnev explains.

As the developers emphasize, the new type of steel will not only produce a significant economic effect, but in the future it will also make it possible to abandon imported equipment and significantly reduce carbon dioxide emissions into the atmosphere.

The project will be presented at the 18th International Festival of Youth Scientific and Technical Creativity “Ot Vinta!” to be held in Sochi on April 26-29.
