    Technological properties

    Name The value
    Microstructure Perlite or pearlitic-ferritic. Graphite: a form - КГф2, КГф3; size - КГД15 - КГД90; distribution - ПГр1 - ПГр3. Perlite: footprint - П70-P45; dispersion - ПД0,3 - ПД1,0. Fosfina the eutectic (nature of distribution) - ФЭр1, ФЭр2. Cementite is not allowed.
    Operating conditions The use of castings made of cast iron notificationname in friction requires careful installation, providing the pair of the friction surfaces and the absence of bias; continuous lubrication, permitting true and significant heating of the friction units; increase of the gap compared to the established bronze 15-30%, in the presence of significant heating osetreni in the work - up to 50%; running at idle and progressively higher loads. At a pressure of P≤0.5 MPa sliding speed V must be ≤5.0 m/s and the product P·V ≤ 2.5 MPa·m/s At a pressure of P≤12,0 MPa sliding speed V must be ≤1.0 m/s and the product P·V ≤ 12,0 MPa·m/s.
