    Description

    Cast iron achv-1 is used: for the production of castings, working in friction with increased peripheral speeds in the pair with tempered or normalized shaft.

    Note

    High strength antifriction cast iron with nodular graphite.

    Technological properties

    Name The value
    Microstructure Perlite or pearlitic-ferritic. Graphite: a form - ШГф2, ШГф4, ШГф5; size - ШГД15 - ШГД180; distribution - ПГр1 - ПГр3. Perlite: footprint - П96-P45; dispersion - ПД0,3 - ПД1,0. Fosfina the eutectic (nature of distribution) - ФЭр1, ФЭр2. Cementite is not more than 5%.
    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 P≤1.5 MPa sliding speed V must be ≤10.0 m/s and the product P·V ≤ 12,0 MPa·m/s At a pressure of P≤20.0 MPa sliding speed V must be ≤1.0 m/s and the product P·V ≤ 20.0 MPa·m/s.
