Role of Niobium in the Evolution of Advanced High Strength Steels
Aiming at the retention of steel in the car body,steel manufacturers are producing and developing a big scope of Advanced High Strength Steels that facilitate weight reduction of critical safety parts,while ensuring crash worthiness,high resistance to intrusion and high absorbed energy.In conjunction with ultra high strength,such steels are being designed for exceedingly high formability including not only elongation,but high bendability and high hole expansion.To meet customer challenges all structure strengthening mechanisms are involved to make sure obtaining the target properties at lower carbon content,at stronger structure refinement and so on.New developments include a big spectrum of Dual- Phase steels,TRIP assisted dual phase steels,and Q&P steels.The presentation,based on laboratory results as well as on literature review,covers the critical role of microalloying by Nb of each type of steel design.
