    摘要: A martensitic stainless steel for a disc brake rotor includes, in mass percent,

    C : 0.04 - 0.10%, Si: at most 1.0%, Mn: 0.1 - 2.0%,
    P: at most 0.04%, S: at most 0.01%,
    Cr: greater than 11.5 to 13.5%, Al: at most 0.1%,
    N: at most 0.04%, Cu: 0 - 1.0%, Ni: 0 - 1.0%,
    Ti: 0 - 0.03%
    and one or more of
    Nb: 0.01 - 0.08% and V: 0.05 - 0.5%,
    with the value of GP expressed by the following formula being at least 50 (%):
    GP (%) = 700C(%) + 800N(%) + 20Ni(%) + 10[Cu(%) + Mn(%)]

    6.2Cr(%) - 9:2Si(%) - 9.3Mo(%)-14V(%) - 74.4Ti(%)
    37.2Al(%) + 63.2.
