Microstructure and Mechanical Properties of 22MnB5 Hot Stamping Part

摘要：

　　Microstructure and mechanical properties of different area of 22MnB5 hot stamping part were analysis by experiment.The results show that the maximum tensile strength reaches 1578MPa at bottom surface area, and the elongation is at the region of 8.5~12 with die cooling area, and the area of bottom surface has higher tensile strength than that of side wall area.Martensite is formed with die cooling, and tempered martensite and undissolved ferrites were found at side wall area.The microstructure of area with air cooling is composed of ferrite and pearlite, and a small amount of martensite.
