Abstract

The need for reducing auto body weight has led to widespread studies and development of high-strength steels over the past decade or so. There are numerous studies on the microstructure–property relationship but little attention has been paid to the challenges in producing these grades without harmful inclusions which affect the performance of final product. Also many of these steels pose difficulties in castability due to clogging as well as harmful inclusions which in themselves are surrogate indicators of cleanliness of steel. This paper seeks to shed some light on the approaches taken by Tata Steel to mitigate such problems in the development of these grades some of which are being commercially supplied and some of which are under development.
