NanoSteel Announces Breakthrough in Steel Design for Automotive Light-Weighting

(Nanowerk News) The NanoSteel® Company, a leader in nano-structured steel materials design, today announced the development of new advanced high-strength steels with exceptional combinations of strength and ductility for automotive structures. NanoSteel has developed three classes of steel with measured strength/elongation performance of 950 MPa/35%, 1200 MPa/30% and 1600 MPa/15% respectively.
NanoSteel’s innovation gives automakers additional ways to use steel in the pursuit of lighter vehicles with better fuel economy without compromising safety. It also allows the auto industry to continue to utilize steel’s existing infrastructure, scale and efficiencies versus switching to other light-weighting materials which may have higher costs, longer cycle times and limited availability.
“These paradigm changing performance levels are enabled by new discoveries related to the formation of nano-scale microstructures (‘nano-structures’),” said Daniel Branagan, Ph.D., CTO and founder of NanoSteel. “Previously, sheet steel made of nano-structures was considered too brittle (no elongation) to form the shapes required for automotive parts. In contrast, NanoSteel’s materials are based on newly discovered mechanisms to form nano-structures during production which eliminate the cause of this brittleness.” NanoSteel’s new AHSS utilizes conventional steel processes and avoids the use of exotic alloying elements.
To date, one of the challenges with currently available AHSS materials is the need to form parts at elevated temperatures – increasing cost and production cycle times. NanoSteel eliminates this extra processing, as the material’s inherent ductility allows the forming of component parts using room temperature metal stamping processes on existing manufacturing equipment, known as cold forming.
“NanoSteel’s patented discovery provides another incentive for automotive OEMs to ‘Stick With Steel™’ as the material of choice for automotive structures and aftermarket servicing,” said David Paratore, president and CEO of NanoSteel. “As such, we are committed to working with our steel production partners to bring our unique family of steels to broad introduction across the automotive industry.”
