Steel Sheet For Hot Stamping And Hot Stamped Molded Body
Abstract: This hot stamped molded body has a metallographic structure having a prescribed chemical composition, the average grain size of old austenite grains being 5-25 µm, and the standard deviation of the grain size of the old austenite grains being 0.1-2.0 µm. Additionally, this steel sheet for hot stamping has a metallographic structure having a prescribed chemical composition, the average pole density of an orientation group composed of ferrite /{100/}<011>-/{223/}<110> being 10.0 or less, the numeric ratio of ferrites that include carbides having an equivalent circle diameter of 0.2 µm or greater in crystal grains among all ferrites being 20% or greater, and perlite and ferrite constituting 10-90% and 10-90% by area ratio, respectively.
