The Research and Development of Hot Stamping Forming Technology and Production Line in View of High Strength Steel Plate

Steel hot stamping is a kind of new forming technology that advanced high strength steel plate will be heated to austenitic temperature then stamping quickly, quenching in pressure stage through the mould and obtaining the cool speed required, thus obtaining the martensite which owns the intensity of around 1500 MPa of ultra high strength. Hot stamping technology of ultra high strength steel plate is one of the important ways which reduces body weight and improves shock resisitance and crashworthiness. Based on the analysis of hot stamping technology and the research present situation, comparing the key equipments and the core technology of the steel plate with each other. The key problem of high strength steel plate hot stamping area is discussed , present situation and the prospect is pointed out.
