Blank hot forming is a new technology which is realized by heating the advanced high strength steel to Austenitic phase,quick stamping,and quenching in die during press holding to meet the required cooling speed.By this new forming technology,the phase of the parts can be changed to martensite,and the strength of the parts can be about 1500MPa.In this paper,Key equipments,key technology,advantage and disadvantage of blank hot forming are introduced,and the application status and trends is proposed.
