Microstructure, mechanical properties, lab formability and ageing response of two as-hot-rolled dual phase steels, a heat treated dual phase steel, and microalloyed 345 MPa and 550 MPa (50 ksi and 80 ksi) steels are compared. Measurements and implications on press performance of work hardening behaviour, strain rate sensitivity, elongation before necking, resistance to edge cracking, and uniformity of properties are discussed. Formability of both heat treated and as-hot-rolled dual phase steels was found to be similar at a common strength level, their formability lying between that of the 345 MPa and 550 MPa steels. (DePo)
