Abstract
Structure and service properties of deposited metal designed for strengthening and reconditioning of various-purpose forming rolls have been studied. Metal deposited with flux-cored wire PP-AN132 has the highest high-temperature resistance, hot hardness and wear resistance at metal-on-metal friction at high temperatures, however, it has the lowest thermal stability. Metal deposited with flux-cored wire PP-AN130 has the highest thermal stability, although it is inferior to other materials as to a number of other indices. Metal deposited with flux-cored wire PP-AN147 takes an intermediate position by all the indices.
