The Study of IF Steel Sheets through Continuous Annealing on Line

This paper has investigated the recrystallization temperatures and structures of interstitial-free (IF) steels with different microalloying elements (MAE) contents, and the formulas between MAE contents and interstitial atoms carbon and nitrogen, which is very useful for practical production, are obtained. Emphasis to discuss the effects of composition and processing parameters on the properties of IF steel. At last, appropriate processing conditions are given.
