A new organic composite-coated steel sheet with bake-hardenability has been developed. The steel sheet consists of Zn-Ni alloy electroplated layer, chromate and zinc powder free organic film. To obtain better formability (anti-powdering) and weldability, the thickness of the organic film is reduced to 0.8∼1.5µm (1.0∼2.0g/m2). The addition of bake-hardenability to this organic coated steel sheet was realized by controlling the amount of residual solute carbon in continuous annealed extra low carbon steels.
