Martensitic Stainless Steel as Alternative for Hot Stamping Steel with High Product of Strength and Ductility

摘要：

　　Though more and more structural and safety automobile components are manufactured using hot stamping technology for the advantage of excellent shape accuracy while producing ultra high strength parts without any springback.Fewer hot stamping steels are developed except22MnB5 steel, which exhibits ultra-high strength but limited ductility.Inspired by the application of quenching and partitioning C-Mn-Si steel, the microstructure and properties of a 30Cr13 steel subjected to quenching and partitioning treatment were studied to evaluate the possibility of martensitic stainless steel as alternative for hot stamping steel with high product of strength and ductility.The experiment result shows that, enhanced mechanical properties of Rel=1350MPa,Rm=1740MPa, and A=17.5% can be achieved through appropriate treatment.Due to the unique phase transformation conditions of martensitic stainless steel, processing parameters and corresponding equipments for automobile components manufacturing have to been investigated.
