c the new method also makes possible mass production of highly durable nanostructured steel with good weldability without softening of haz during welding including thin sheets and armature in the production of steel for mass consumption the new method allows using less of alloying elements including decrease of consumption of manganese in manganese containing substances by 60 and by 50 of nickel in nickel steel a significant increase of quality and decrease of expenses of production of steel products could only be achieved by significantly changing current technological processes of steel production including firstly making a change in the steel alloying which is most costly but also is the most important for changing the formation of improved physical properties and quality of steel the inventors have resolved an objective of changing processes of alloying and modification of steel not through perfection of traditional schemes of alloying with the use of expensive materials including application of even more expensive rare earth elements but through the change of physico chemical processes of alloying and modification of steel that change the very nature of alloying and modification for these reasons in the present application for new technologies of alloying and modification of steel atomic nitrogen has been offered as the main alloying element as it possesses unique physico chemical properties.
