This paper considers the possibility of creating cast rods for surfacing of rapidly-wearing tillage tool parts of agricultural machinery, which would not contain scarce alloying elements and provide a wear-resistant deposited metal having high hardness and high resistance to crack formation in hardened condition. It was found that with an increase in boron concentration to 0.7 … 0.8%, the amount of boride eutectic increases, which helps to prevent crystallization cracks, and the impact toughness first increases, and then slightly decreases, which is associated with the appearance of large boride inclusions.
