Abstract：To improve aging resistance of hot-dip galvanized low carbon aluminum killed steel sheet, the effect of coiling temperature on aging resistance was investigated by measuring aging index and internal friction of galvanized sheets. The results show that in the range of 620-710℃ higher coiling temperature leads to less solid solution carbon and better aging resistance of galvanized sheet. Aging index decreases 19 percent by increasing coiling temperature from 620 to 710℃. Properly increasing coiling temperature is one of the effective ways to improve aging resistance of hot-dip galvanized low carbon aluminum killed steel sheet.
