A new technique to manufacture cold rolled ultra high strength steel sheets through the continuous annealing line with a water quenching device has been developed. Full martensite and ferrite plus martensite dual phase steels with 80 to 150 kgf/mm^2 in tensile strength can be easily obtained by water quenching after annealing in the austenite and ferrite plus austenite regions, respectively. These products having good formability and weldability are used successfully for automobile parts to improve the safety of the passengers in case of an accident and to reduce the weight of the automobiles. Furthermore, these products are being utilized in the industry of construction, and are expected to be used for machinery, electric appliances, containers, and others.
