It is shown that the use of nickel provides the grain refinement of austenite, the dispersion of the needles of martensite promotes the formation of carbides dispersed structure, which may have an impact on improving thermal rolls, increases the microhardness of martensite and the hardness of the deposited steel, reduces abrasive wear of weld layers. Introduction to the composition of the charge carbon-fluorine containing additives enhancing the properties of steel surfaced: increased hardness and reduced abrasion of the deposited layer. Keywords Welding, flux, metal, slag, flux cored wire, welding, microhardness, hardness, speed of abrasion Funding The work is done in sibsiu as part of the project part of State task of Ministry of education and science of the Russian Federation No. 11.1531.2014/K. When testing, research, and measurement was used the equipment of collective use Center "Materials Science" sibsiu.
