A hot press forming steel directly rolled through a medium-thin slab and with tensile strength not less than 1100MPa comprises the following components in percentage by weight: 0.12-0.16% of C, 0.15-0.20% of Si, 0.7-1.0% of Mn, not greater than 0.02% of P, not greater than 0.008% of S, 0.015-0.060% of Als, 0.15-0.20% of Cr, 0.005-0.02% of Ti, or 0.005-0.02% of Nb, or 0.005-0.02% of V, or a mixture of more than two of Ti, Nb and V in any ratio, 0.0005-0.0020% of B, 0.10-0.13% of Mo, and not greater than 0.005% of N. The production method comprises the following steps: desulfurizing molten iron; smelting and refining through an electric furnace or a converter; continuously casting; removing scale before entering a soaking pit; soaking; heating; removing scale through high pressure water before entering a rolling machine; rolling; cooling; coiling; austenitizing; punching and forming through a die; and quenching. The production method is short in process; the product surface quality is good, and the thickness accuracy is high; the quality requirement of a cold-rolled product can be met; the complex deformation can be finished smoothly; in addition, the resilience is avoided after the deformation; the size accuracy of a part is high.
