Abstract

Several types of hot-rolled dual-phase sheet steels prepared by simple temperature control in hot strip mill or by heat treatment on a continuous annealing line have been compared in this investigation with conventional microalloyed steels through various forming tests. Thickness of these steels ranges from 1.8 to 2.5 mm and yield strength from 300 to 520 MPa. Forming tests employed include stretching, drawing, flange stretching or hole expansion, and simulative model forming of automotive parts such as rear axle housing and spring support, and the behavior of these sheets is discussed in detail.
