Abstract

The invention discloses a hot stamping forming steel board for restraining falling off of an oxide layer in the hot stamping process and a production method thereof. The hot stamping forming steel board comprises, by weight, 0.19%-0.27% of C, at most 0.50% of Si, 1.00%-1.50% of Mn, at least 0.010% of Al, at most 0.010% of N, 0.01%-0.055% of Ti, at most 0.35% of Cr, 0.0005%-0.004% of B, at most 0.50% of one or more of Mo, W, Cu and Ni and at most 0.10% of one or more of Nb, Zr and V, and the surface roughness of the steel board is 1.1-2.0 microns. The production method comprises the following steps that a, steel board raw materials are obtained according to the elements of the claim 1; b, roughness treatment is conducted; and c, hot stamping forming steel is obtained.

Description

technical field [0001] The invention relates to a hot stamping formed steel plate and a production method thereof, in particular to a production method of a hot stamped formed steel plate which can suppress the loss of an oxide layer during the hot stamping process. Background technique [0002] With the rapid development and progress of science and technology, the technology of various industries is also constantly innovating, and the application requirements for hot stamping steel sheets and the technical requirements for production and use are also increasing. Taking the field of automobile manufacturing as an example, due to the pressure on environmental protection, to achieve energy saving and emission reduction, it is necessary to consider the various components of automobile products, and to achieve light weight of the car body and collision safety can largely achieve product quality. Innovation and progress, and the car body began to gradually adopt the steel plate m...
