<p>Disclosed is a hot pressed member having a tensile strength (TS) of 980-2130 MPa, which is reduced in decrease of the surface hardness. Also disclosed are a steel sheet for the hot pressed member, and a method for producing the hot pressed member. The hot pressed member is characterized by having a composition that contains, in mass%, 0.09-0.38% of C, 0.05-2.0% of Si, 0.5-3.0% of Mn, 0.05% or less of P, 0.05% or less of S, 0.005-0.1% of Al, 0.01% or less of N and 0.002-0.03% of Sb with the balance made up of Fe and unavoidable impurities. The hot pressed member is also characterized by having a tensile strength (TS) of 980-2130 MPa.</p> |
