Development on a New Interstitial-Free Steel with △r ≤0.3

Abstract:

Traditional IF steel is Ti-IF steel for low cost. Some car producer require IF steel to have good mechanical properties with low delta r (plastic stain ratio) value (△r) as well as high performance after welding. A new IF steel was developed by adjusting amount of Nb and Ti based on Ti-IF steel and employing suitable parameters in manufacturing processes. Annealing experiments were made to decide reasonable annealing temperature. The final products exhibit good isotropy with △r ≤0.3. This new type IF steel also had good performances after welding by analyzing results of some key parameters, which can totally meet requirement of car producer.
