Si: 0.01% to 1.50%;
Mn: 0.10% to 2.50%;
Cr: 5% to 15%;
Ni: 0.05% to 1.50%;
Mo: 0.1% to 2.0%;
V: 0.1% to 1.0%;
Nb: 0.01% to 0.20%;
a rare earth metal element (REM): 0.012% to 0.050%;
S: 0.0010% to 0.0200%; and
O: 0.025% or less, including 0%,
wherein 3.0≤(Nb+10×REM)/(S+O)≤200.0,
wherein the REM comprises La and Ce, and a mass ratio of La to Ce satisfies:
