The laser thermal hardening and cladding are promising technologies in the production process of forming rolls. It is shown that laser technologies enable purposeful formation of the microstructure of the surface of the product and get a new set of high mechanical and performance properties. The structure and properties of the surface layers of steels with different carbon contents. Set of studies included a definition of the physical and mechanical properties of materials by standard techniques to study the structure of the samples. Laser powder cladding in a single pass allows you to create a surface layer with specified thickness up to 1.5 mm multi-layer surfacing produces modified layers with the geometric dimensions defined specifications for the product. The additional laser treatment tends to equalize the level of each of the microhardness of the material across the longitudinal plane of the surface layer.
