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.sup.-1) in a temperature range of 800.degree. to 300.degree. C. in at least one pass when the low carbon steel is rolled into a specified thickness, and subsequently performing recrystallization annealing.

A process for producing a formable thin steel sheet excellent in ridging resistance, which comprises finish rolling a low carbon steel at a strain rate (.epsilon.) of not less than 300 (s.sup.-1) in a temperature range of 800.degree. to 300.degree. C. in at least one pass when the low carbon steel is rolled into a specified thickness, and subsequently subjecting said sheet to recrystallization annealing.
