Abstract:
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.

Claim (Index 15):
The method according to  claim 11 , wherein the steel strip is high strength cold rolled TRIP assisted dual phase steel strip, comprising the steps of:\n a) the cast steel undergoes said hot-rolling to the thickness of 2.0-4.0 mm and coiled at the coiling temperature C T  wherein the coiled hot-rolled steel strip has the microstructure consisting of 40-80 volume % ferrite, 20-50 volume % pearlite and/or bainite, and less than 10 volume % cementite/precipitates/inclusions, the sum adds up to 100%, b) the strip undergoes said pickling, c) the strip then undergoes said cold-rolling with a reduction of 40% or more, d) the strip undergoes the annealing heat treatment between transformation temperatures A c1  and A c3 , followed by one or more cooling phases at a cooling rate V cs  when the temperature is below A c3 , followed by a overage phase at an overage temperature T oa  for a overage time t oa , being chosen in such a way that the microstructure of said steel consists of ferrite, bainite, residual austenite and, optionally martensite and/or cementite, e) optionally the annealed strip undergoes the quenching and partitioning or quenching and tempering in the overage section, f) the strip undergoes said hot-dip galvanised galvanizing, g) the strip undergoes said temper rolling with an elongation of less than 0.7%, preferably less than 0.5%.
