Abstract
Pre-coated steel sheet with aluminum or aluminum alloy pre-coating, manufacturing method and hot stamped components, where the method for manufacturing a pre-coated steel sheet with aluminum or aluminum alloy pre-coating relates to the situation of 0.10%≤C≤0.30%, the dew point of the mixed atmosphere is controlled in the range of −40˜−15° C. and, where it relates to the situation of 0.30%<C≤0.50%, the dew point of the mixed atmosphere is controlled in the range of −36˜−12° C. A pre-coated steel sheet with aluminum or aluminum alloy pre-coating is obtained by the method and hot stamping components are obtained by the pre-coated steel sheet. The improved toughness and VDA peak force are achieved for the hot stamping components and then the collision safety of hot stamping components is elevated.
