The US Department of Energy (DOE) has offered a $730-million conditional loan commitment to Severstal Dearborn, LLC. The funding will support the modernization of existing facilities in Dearborn, Michigan, in addition to the design, manufacture, and construction of new facilities to produce the next generation of automotive advanced high strength steel (AHSS).
The facilities will produce a wide range of advanced high strength steels, which will enable manufacturers to reduce the weight of steel components used in vehicles, creating a 10% reduction in total vehicle weight while meeting increasingly stringent safety regulations. Severstal’s AHSS project has the potential to reduce petroleum-based fuels consumption by nearly 30 million gallons annually, and thus avoid over 260,000 metric tons of carbon dioxide emissions.
Future Steel Vehicle Program. Severstal is one of 17 global steel makers to complete Phase 2 of the Future Steel Vehicle program (FSV). FSV has added the most advanced steel products and technologies to its portfolio, utilizing more than 20 new Advanced High Strength Steel (AHSS) grades, representing materials expected to be commercially available in the 2015 – 2020 technology timeline.
The FSV material portfolio includes dual phase (DP); transformation-induced plasticity (TRIP); twinning-induced plasticity (TWIP); complex phase (CP); and hot formed (HF) steels, which reach into GigaPascal-strength levels and are the newest in steel technology offered by the global industry.
As announced by the WorldAutoSteel organization in May, the FutureSteelVehicle (FSV) features steel body structure designs that reduce mass by more than 35% over a benchmark vehicle and reduce total life cycle emissions by nearly 70%. This is accomplished while meeting a broad list of global crash and durability requirements, enabling five-star safety ratings, while avoiding high-cost penalties for mass reduction.
The FSV program developed optimized Advanced High-Strength Steel (AHSS) body structures for four proposed 2015-2020 model-year vehicles: battery electric (BEV) and plug-in hybrid electric (PHEV) A-/ B-Class vehicles; and PHEV and fuel cell (FCEV) C-/D-Class vehicles.
FSV’s BEV concept weighs 188 kg and reduces mass by more than 35% over a baseline ICE body structure adjusted for a battery electric powertrain and year 2020 regulatory requirements. FSV’s A-/ B-Class PHEV20 vehicle weighs 175 kg, and the larger C-/ D-Class vehicle versions weigh 201 kg.
