Hot stamping is a new forming technology which can improve the forming ability of high strength steel, ensure the dimension precision and improve the strength level of parts. Based on introduction of hot stamping process and application for ultra high strength steel, the main factors affected the quality of hot stamping parts were identified and analyzed, effect of the die material and die cooling design, the hot stamping parameters, such as austenitic temperature, heat time, cool speed and pressure holding time on the quality of hot stamping parts were discussed. These provide references for the quality control of hot stamping parts during the vehicle manufacturing.
