Dual phase (DP) steel is a high strength steel for auto-panel. In this paper, mechanical property, forming ability, baked-hardening and work hardening properties of high strength steel DP450 are studied by experiments, and compared with those of steel MS6000.And theoretical research on predicting the forming limit of steel DP450 by the NADDRG model. The established mathematic model for relativity is of practical usefulness. Experimental results reveal that the yield strength of steel DP450 is about 7.2% lower than the MS6000,and the break strength increases by 18.9%,while the elongation increases by 19%.The strain hardening exponent of steel DP450 are superior to those of MS6000.The results show that mechanical property of high strength steel DP450 is better than that of MS6000,while forming ability of DP450 is not lower than that of MS6000.And baked-hardening and work hardening properties of steel DP450 are better than those of MS6000.The steel sheet DP450 owned a good forming ability.

Design And Testing

This paper explores an innovative solution based on the geometric redesign of integrant safety shoe`s component, the toe cap component. The investigation program covered some steps as the computational modeling of the toecap component, a set of numerical simulations in the FEM context with the toecap model discretization used for multiple Non-Linear Analysis on plastic domain, and experimental tests for ISO EN 20345 certification to support and comparing results. The aim of the study is to explore the work hardening phenomenon of the high strength steel DP600 on toecap component formed, to predict an expected mechanical strength increase and a consequent significant reduction of the weight. The study points to a thickness decreasing value of approximately 50% and equivalent reduce of weight.
