Properties of deposited metal used for metallurgical tool hardening

G.N. Sokolov

Volgograd State Technical University, Volgograd, RF

Abstract
Problems associated with rational alloying of deposited metal of the Ni-Cr-Mo-Nb-C system to provide hardening of metallurgical tool operating at temperatures up to 900 °C are considered. The effect of molybdenum and niobium content on high-temperature hardness, susceptibility to hot cracking and heat resistance of deposited metal has been studied.
Keywords: arc hardfacing, high-alloy deposited metal, high-temperature strength, heat resistance, hot cracks, fluxcored wire
