Abstract
It is shown that under the influence of alloying (Cr, Mn, C, Si, Ti, N, V) during
electric arc hardfacing with a flux cored wire, as well as technological tempering parameters at
temperatures of 300–700 °C, the phase-structural composition of the cost-saving alloyed deposited
steel (from 0 to 75 % quenching martensite and austenite), the degree of metastability of austenite
are regulated. At optimal parameters of alloying and tempering, an increased wear resistance is
achieved due to the development of the deformation induced martensite γ→α' transformation of
austenite during the wear process, which causes the effect of self-strengthening during testing and
operation. This is an important advantage of the developed metastable deposited steel before the
deformation-stable metal.
