Abstract
A cold rolled and hot dip coated steel sheet presenting a tensile strength above 1000−50×Al MPa, a uniform elongation above 15% and a low density is provided. The steel includes, by weight percent: The balance being Fe and impurities and the microstructure containing 25% to 90% of ferrite, 10% to 50% of austenite, kappa precipitates lower than 5% and martensite lower than 25%. The steel is able to be coated using total oxidation.
