Abstract: Nowadays, high strength steels are being increasingly used in the automotive industry and hot stamping of high strength steel plays an important role of light weighting without affecting the structural performances of final products. Unlike the cold stamping process, blank is formed and quenched, simultaneously during the hot stamping process. This affords the opportunity to manufacture components with complex geometric shapes and high strength. In this paper, the hot and cold forming simulations of a prototype model are processed with Usibor 1500 steel. The forming simulations are performed by DYNAFORM. For this purpose, tensile tests are implemented at elevated and room temperatures. Mat 106 and Mat 18 material models are selected for the hot and cold stampings, respectively. The results from the simulations show that the hot stamping process is safer than cold stamping.
