The demands by the automotive industries to meet the environmental concerns such as global warming, CO2 emissions etc. require materials for weight saving for fuel efficiency. Among the metallic materials that would meet these conflicting demands, steel has been proved to be the only choice available yet. The reduction in sheet thickness by use of high strength steel is being increasingly adopted as an effective means for weight reduction and increase in payload. In this paper Essar Steel's experience in development of high strength S650MC/80Ksi grades steels for long member application in heavy duty commercial trucks is presented. These grades have been substituted in place of conventional 420 and 460 MPa strength steels. These high strength grades are designed to meet the complex loading behaviour of long members and also provide significant weight saving potential. Details of metallurgical product strengthening, design principles, performance of material in actual line production are presented.
