Abstract

This steel sheet for hot stamping has a prescribed chemical composition, and has a metal structure in which S<sub>α</sub>+S<sub>GB</sub>, which is the sum of the area percentage S<sub>α</sub> of ferrite and the area percentage S<sub>GB</sub> of granular bainite, is greater than or equal to 10% but less than 50%, and S<sub>GB</sub>/S<sub>α</sub>, which is the ratio between the area percentage S<sub>GB</sub> of granular bainite and the area percentage S<sub>α</sub> of ferrite, is 0.30-0.70. A hot stamping molded body produced with this steel sheet for hot stamping has a prescribed chemical composition, has a metal structure in which the average prior austenite grain size is 5-25 μm and the standard deviation of the prior austenite grain size distribution is 0.1-2.0 μm, and has a tensile strength of 2,200 MPa or more.
