The invention relates to the field of metallurgy, in particular to the composition of cast heat-resistant alloy. The cast heat-resistant alloy contains following components, wt. %: 0.6-1.4 of carbon, 18.0-21.0 of chrome, 1.52-2.5 of silicon, 2.0-3.5 of manganese, 1.3-0.6 of titanium, 0.01-0.2 of aluminium, 0.01-0.05 of nitrogen, iron and admixtures are the rest. The invention provides for increasing gas abrasive and hot abrasive wear resistance sufficient heat-resistance in heat cycling of alloy to 700 DEGREE C and reduction of alloy manufacturing cost by 30-40 %.
