Abstract: Referring to the standard “VDA 238-100 Plate Bending Test for Sheet Metal” and GB/T 228.1-2010 to study the ultimate tip cold bending and mechanical properties of ultra-high strength hot forming steel, the results show that the tensile strength of Nb+Ti composite microalloyed hot forming steel increases significantly with the increase of cooling rate, and the ultimate tip cold bending angle does not change much. On the contrary, the effect of cooling rates on the mechanical properties of Nb+Ti+V composite microalloyed steel is small, because the addition of V provides sufficient hardenability to obtain a fully martensitic microstructure at lower cooling rates. At higher cooling rates or larger ultimate tip cold bending angles, the addition of V improves the mechanical properties and cold bending properties of the hot forming steels more significantly.
