FIELD: metallurgy.
SUBSTANCE: casting from alloyed white foundry cast-iron is described. The casting is made from white cast-iron containing the following, wt %: chrome 12-25; carbon 1.5-6; manganese 2-7; silicon up to 1.5; molybdenum up to 2; nickel up to 4; microalloying elements chosen from the group consisting of titanium, zirconium, niobium, boron, vanadium and tungsten up to 2 of every one or more elements; and iron is the rest. Microstructure of casting contains 15-60 vol % eutectic carbides and primary carbides dispersed in iron-containing matrix that contains martensite and is at least free from perlite.
EFFECT: casting has high hardness and wear resistance.
