    Description

    60Х3Г8Н8В 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).

    Fe is the basis.
    At the discretion of the manufacturer, tungsten in steel 60Х3Г8Н8В can be replaced with vanadium (mass fraction - 0,5-1,0%). In this case, the designation of the steel grade is changed to 60X3G8N8F. When melting steel 60Х3Г8Н8В by remelting with the use of waste steel 60Х3Г8Н8Ф in it the presence of residual tungsten (mass fraction up to 0,5%) is allowed.
