Abstract:The recently developed CH-W® 800 hot-rolled steel is specifically developed for automotive chassis applications that require both high strength and outstanding formability. A completely ferritic microstructure allows hole expansion ratios of 90% and more, which indicates the remarkable formability of the material. The tensile strength of at least 800 MPa is mainly due to its very fine-grained microstructure as well as titanium carbide nanoprecipitates.
