In the current stage of development of our society, it becomes impossible to think of the world without iron and steel. The production of steel is a strong indicator of a country's stage of economic development. Its consumption grows proportionally to the construction of buildings, execution of public constructions, installation of means of communication and production of equipment.

The beginning and the perfecting process of the use of iron represented great challenges and achievements by mankind.
