A steel strip or sheet having a complex phase microstructure including one or more of ferrite, carbide free bainite, martensite and/or retained austenite in its microstructure including:

High strength hot rolled or cold rolled and annealed steel and method of producing it

A high strength hot dip galvanised steel strip consisting, in mass percent, of the following elements: 0.10-0.21% C, 1.45-2.20% Mn, max. 1.50% Si, 0.1-1.50% Al, 0.001-0.04% P, 0.0005-0.005% B, 0.005-0.30% V, max. 0.015% N, max. 0.05% S, and, optionally, one or more elements: max. 0.004% Ca, max. 0.10% Nb, max. 0.50% Cr, max. 0.20% Mo, max. 0.20%, Ni, max. 0.20% Cu, and max. 0.20% Ti the balance of the composition consisting of Fe and inevitable impurities. The steel has good surface finish and increased mechanical strength, in particular high overall strength, ductility and plasticity. It also relates to a process for the manufacture of a high strength hot dip galvanised steel strip and to the products thereof.
