    Technological properties

    Name The value
    Macrostructure and pollution The macrostructure of cast iron in areas of machining should not have a chill.
    Features of heat treatment The hardness test performed for each lot of castings of one melting before annealing. When you bleach or increased hardness of the casting should be held by their heat treatment in the following mode: Heating to a temperature 900-950 °C (exposure 2-5 hours) + Cooling with the furnace to 600 °C + Further air cooling. When deciding on the necessity of annealing, the inspection of hardness is carried out after annealing. In the case of negative results after carrying out annealing batch of casting is rejected.
    Wear resistance Operating conditions of casting: Wednesday - produced fluid (mixture of oil, associated water and oil gas); the pH of the associated water pH 6,0-8,5; maximum mass concentration of solid particles to 0.01% (0,: g/l); the microhardness of the particles is not more than 5 points Mohs; the maximum mass concentration of hydrogen sulfide is 0.001% (0.01 g/l); the maximum content of associated water 99%;
