Material Notes:

Available in the following: uncoated (HDT450F) and Extragal® (HDT450F+Z)Description: This range of hot-rolled high strength steels has been developed to meet weight reduction requirements. It comprises four strength levels: FB 450, 540, 560 and 590. This family of steels extends the HSLA range of micro-alloyed steels to include products combining high tensile strength (UTS) with excellent formability and hole expansion (stretch flangeability) based on their ferrite-bainite microstructure.Applications: These steels are cold-drawn. The main applications are:structural parts (longitudinal beams, cross beams, car-body and ground liason parts),wheels,mechanical parts (ground liason parts, gear boxes...).ArcelorMittal has an extensive database relating to the forming and service properties of the entire range of ferrite-bainite steels. To integrate these steels at the design stage, a team of experts is available to perform specific studies based on modeling or laboratory tests.Information provided by ArcelorMittal
