Some Performance Aspects of Dual-Phase Steels in Comparison to HSLA, C-Mn and TRIP Steels 2004-01-0505

Hot-dip coated dual-phase steels, with tensile strengths of 490 and 590 MPa, have been developed and are being successfully applied in several automotive structural applications. The tensile properties are achieved through alloying with manganese and molybdenum. This paper compares some performance aspects viz., strain-hardening, sheared-edge stretching, stretch forming, drawing and bake-hardening of these dual-phase steels to other high-strength (HSLA and C-Mn) and advanced-high-strength (TRIP) steels. The spot-welding behaviors of the dual-phase steels are also described.
