Abstract

To study the effects of baking temperature on the three-point bending properties of 1800 MPa hot stamping steel, cold-rolled 1800 MPa hot stamping steel with Al-Si coating was used. The heating condition was 930 ℃ for 300 s, after hot stamping, the samples were baking under 140 ℃, 170 ℃, 200 ℃, 230 ℃ and 260℃ respectively. SEM were used to analysis the microstructure of the samples. The bending tests were carried out according to VDA 238-100. The results show that baking process can effectively improve the bending properties of 1800 MPa hot stamping steel. After baking under 260 ℃, the bending angle increased by 43%. After baking, the microstructure is martensite, tempered martensite and carbides. In conclusion, baking process can improve the three-point bending properties of 1800 MPa hot stamping steel.
