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(%)
