Production of formable thin steel sheet excellent in ridging resistance

摘要

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.
