Abstract
Investigation results of influence of rare-earth metals on structure and properties of medium-chromium deposits were presented. It is shown that effect of the rare-earth metal additives appears in increase of technological strength, impact toughness and resistance to thermal fatigue failure of metal used for hardfacing of rollers of hot rolling.
