    Description

    60Х3Г8Н8Ф steel is used: for the manufacture of retaining rings of turbogenerators and other parts of the engineering requirements of namagnichennosti.

    Note

    The austenitic steel.
    Absolute magnetic permeability at field strength of 1.6·104 A/m (200Э) must not exceed 1.4 x 10-6 Ng/m (1,1 GS/e).
    Electrical resistivity shall not be less than 0,65·10-6 Ohm·m (0.65-Ohm·mm2/m).
