摘要（英）：

The invention, as-rolled steel sheet for press cure, press for curing chemical compositions is 0.24% ≤ C ≤ 0.38%, 0.40% ≤ Mn ≤ 3%, 0.10% ≤ Si ≤ 0.70% as the content expressed in wt. , 0.015% ≤ Al ≤ 0.070%, 0% ≤ Cr ≤ 2%, 0.25% ≤ Ni ≤ 2%, 0.015% ≤ Ti ≤ 0.10%, 0% ≤ Nb ≤ 0.060%, 0.0005% ≤ B ≤ 0.0040%, 0.003 % ≤ N ≤ 0.010%, 0.0001% ≤ S ≤ 0.005%, 0.0001% ≤ P ≤ 0.025%, and including, the titanium and nitrogen content satisfying the Ti / N> 3.42, carbon, manganese, chromium and silicon content of the The satisfaction and the chemical composition of the following elements: including 0.05% ≤ Mo ≤ 0.65%, 0.001% ≤ W ≤ 0.30%, at least one of 0.0005% ≤ Ca ≤ 0.005% optionally, and the balance being iron and manufacturing unavoidable made of impurity, and the sheet is deep over the Δ and at any point in the river near the surface of the sheet containing Ni _surf> Ni _nom the nickel content of Ni _surf, where Ni _nom is the nominal nickel content of the river caused by a represents, as the Ni _max indicates the maximum nickel content within Δ, ego, , Where the depth Δ is expressed in microns, and the content of Ni and Ni _max _nom is directed to a rolled steel sheet for press hardening, which is expressed by weight%.
