The forming characteristics of advanced high strength steel are studied in this paper based on the experimental study and simulation of formability, springback and galling. It is shown that compared to conventional HSLA steel, DP steel and TRIP steel have relatively higher ability to ensure the strain distribution much evener and obtain much higher formability, which will improve the part strengths remarkably. The steel grade and material mechanical parameters have obvious effect on the spring-back, which will increase the difficulty to control the dimension precision of high strength steel. With the increase of steel strength, the galling defects are much easier to occur.
