Abstract
A steel strip is produced having a tensile strength of at least 680 MPa but is such that the total elongation to break off of the strip after annealing is in the range 9% to 12%. Cold rolling may produce a cold reduction of the strip thickness in the range 40% to 80%. The continuously cast strip may be optionally in-line hot rolled prior to coiling to produce an initial strip thickness in the range 40% to 60%.
