Abstract: Disclosed in the present invention are a hot stamped steel plate with Al—Zn—Mg—Si plating and a hot stamping method therefor; before hot stamping, the initial structure of the Al—Zn—Mg—Si plating is composed of a Zn-rich phase, an Al-rich phase, a MgZn2 phase, an MgSi2 phase, and a Fe—Al—Si alloy layer; after hot stamping, when the heat preservation time of the plating structure is t?3 min, the plating is composed of an upper and lower layer, the structure of the first layer being composed of an Al-rich phase, a Zn-rich phase, and an MgZn2 phase, and the volume percentage ratio of the sum of the Zn phase and the MgZn2 phase is between 20% and 80%; the structure of the second layer is composed of an FeAl3 phase and a Zn-rich phase, and the volume percentage ratio of the Zn-rich phase does not exceed 5%; when the heat preservation time is t>3 min, the plating is composed of a single-layer alloy layer, and the alloy layer is mostly composed of a FeAl3 phase, wherein a Zn-rich phase and an MgZn2 phase are pres

Abstract: A hot stamping component having a tensile strength ?1000 MPa and a fabrication method therefor. The chemical composition of said hot stamping component by weight percentage is as follows: 0.05-0.20% of C, 0.02-1.00% of Si, 0.5-2.0% of Mn, P?0.10%, S?0.05%, 0.01-0.30% of Al, 0.01-0.04% of Nb, 0.01-0.06% of Ti, 0.12-0.50% of Cr, and 0.001-0.05% of B, and the remainder is Fe and other inevitable impurities; in addition, the following must also be satisfied: 0.24%?C+Mn/6?0.45%, and 0.05%?Nb+Ti+B×10?0.15%. With regard to the obtained hot stamping component, the original austenite average grain size is ?10 ?m, the VDA cold bending angle is ?80°, the room temperature impact toughness is ?80 J/cm2, the yield strength is ?800 MPa, the tensile strength is ?1000 MPa, and the elongation at break is ?6%. The hot stamping component has high toughness while also having high strength, and can therefore be widely applied in automobiles, ships, machinery, and other industries.

Abstract: A method for forming a zinc-plated steel plate or steel belt having good corrosion resistance, comprising the following steps: 1) conveying the steel plate or steel belt into a heating furnace higher than Ac3, austenitizing the steel plate or steel belt, and keeping the temperature for 1-7 minutes; 2) before the steel plate or steel belt leaves the heating furnace and enters a forming mold, applying different cooling manners according to different plated thicknesses, wherein when the single-sided weight of the plating is less than or equal to 50 g/m2, only air cooling is required before transferring to the forming mold, when the single-sided weight of the plating is greater than 50 g/m2, aerial fog or water mist precooling is performed before transferring to the forming mold, and the steel plate is cooled to be below 700° C. at a cooling sped greater than 30° C.
