Nissan Motor Co., Ltd. announced in late 2011 the world’s first* Ultra High Tensile Strength Steel rated at 1.2 gigapascals (GPa) which is highly formable, to the extent that it can be used for cold pressing structural body parts. To be deployed globally in models across the Nissan lineup from 2013, it will reduce vehicle body weight by up to 15 kilograms, representing a significant step in improving environmental impact as well as driving performance.

Mazda Motor Corporation, in collaboration with Sumitomo Metal Industries, Ltd. and Aisin Takaoka Co., Ltd., has become the first automaker to successfully develop vehicle components using 1,800 MPa ultra-high tensile steel. The super strength steel will debut in the all-new Mazda CX-5 crossover SUV that will commence its global launch in early 2012.
