with higher strenght,weight reduction can be achived.Besides the required tonnage,formability and weldability have an important influence on the costs os a construction.furthermore,sufficient toughness is a pre-requisite to guarantee structural integrity.A low carbon bainitic microstructure offers a good combination of these properties for steel with yield strenght above.
