Development of Nb containing steel at SAIL for automotive application: present status and future prospect

The automotive industry has encouraged steel producers to develop high strength formable steels in both hot rolled and cold rolled gauges. The paper discusses the measures by SAIL to meet the expectation of the customers. Hot rolled high strength steels micro-alloyed with niobium have been developed for auto chassis application whereas high strength cold rolled grades have been developed for moderate forming application. The developmental work for dual phase, TRIP and ultra fine-grained steel has also been highlighted. (AU)
