Изобретение относитс  к области изыскани  материалов, предназначенных дл  изготовлени  деталей, работающих в услови х повышенного изнапливани .The invention relates to the field of finding materials intended for the manufacture of parts operating under conditions of increased melting.

Известен чугун, содержащий хром и марганец .Known cast iron containing chromium and manganese.

Иредложенный чугун отличаетс  от известного дополнительным легированием бором и титаном. Это обеспечивает предложенному чугуну повышенную износостойкость и обрабатываемость резанием. Чугун имеет следуюш.ий состав, %: Углерод2,5-3,2The proposed cast iron is different from the known additional doping with boron and titanium. This provides the proposed cast iron increased wear resistance and machinability. Cast iron has the following composition,%: Carbon 2.5-3.2

Твердость чугуна составл ет: В литом состо нии52-56 HRCThe hardness of the iron is: In a cast state 52-56 HRC

В закаленном состо нии 58-63 HRC В отожженном состо нии 320-360 НВ Иредел прочности при изгибе 70- 100 кг/мм. Дл  повышени  износостойкости чугун закаливают от 950-980°С с охлаждением на воздухе. Обрабатываемость предложенного чугуна в 1,75-1,85 раза выше, чем аналогичного чугуна без бора и титана.In the hardened state 58-63 HRC In the annealed state 320-360 HB and bending strength 70-100 kg / mm. To increase wear resistance, the cast iron is quenched from 950-980 ° C with air cooling. The machinability of the proposed iron is 1.75-1.85 times higher than that of similar iron without boron and titanium.
