Abstract :Deep drawing is one of the most important and vastly conducted sheet metal forming method. Thus, even small improvements achieved on the deep drawability of sheet metals significantly increases the ability of sheet metal to be formed into more complex products. Advanced high strength steels insert ignore into journalissuearticles values(AHSSs); are one of the most popular steels in the automotive industry due to their high strengths. However, their low ductility causes considerable splitting problems on the shop floors. In this study, deep drawing experiments have been conducted in conical dies with four different angles insert ignore into journalissuearticles values(0⁰, 7.5⁰, 12.5⁰, and 20⁰); for DP800 and MART1400 steels to observe whether a higher deep drawing ratio insert ignore into journalissuearticles values(DDR); can be achieved by deep drawing in conical dies for AHSSs. In addition, finite element analysis insert ignore into journalissuearticles values(FEA); has been utilized to estimate the DDR for each types of steels in different conical die setups. It has been observed that the deep drawing ability of MART1400 steel has not improved in any of the conical die setups. However, DDR of DP800 has slightly increased by 2.46% by deep drawing with 20⁰ die angle. A good agreement with the numerical and experimental results has been achieved.
