Nowadays high-strength wear-resistant steels are the most promising materials in machine-building production. The application of these steels in Russia dates back to the early 1990–s and they are in great demand.

No doubt there is a close link between the use of new materials and industrial production competitiveness. Manufacturers of various industrial equipment and machines are ever more required to increase production efficiency and extend the service life of the equipment, reduce material consumption, lower operating costs, meet environmental requirements. All this leads to the development and use of the new steel grades with improved properties in industry, in particular – special high-strength steels [1].

The application of high-strength structural steels makes it possible to achieve noticeable cost optimization in the production cycle. There are some advantages in the machine design manufacture of thinner sheets: significantly reduced cost of welding materials, reduced duration of welding, as well as the amount of harmful atmospheric emissions. In addition, transport costs for material moving to the place of products manufacture are lowered, particularly in case of using a large amount of metal. This increases the efficiency of the equipment and reduces production costs. This steel has rather high impact toughness at lower temperatures, that’s why it is extensively employed in equipment fabrication in the North [2].
