Abstract:
    A process for producing a formable thin steel sheet excellent in ridging resistance. Said process comprises finishing a low carbon steel at a strain rate of not less than 300 (s-1) in a temperature range of 800 DEG to 300 DEG C in at least one pass when the low carbon steel is rolled into a specified thickness, and subsequently performing recrystallization annealing.
