New Nissans will be 25% of high -strength steel

Nissan Motor Co Ltd has announced its plans to expand the use of advanced high -strength steels in the production of new car models. The mass fraction of high -quality steel will be brought to 25%.

The use of high -strength steels is one of the initiatives of the design unit of the automobile company aimed at reducing the weight of the machine. Engineers Nissan developed “High -strength steel” ultra with a limit of 1.2 gigapasals (GPA). For comparison, the usual steel used in mechanical engineering has a strength limit of the 1 not more than 0.7 GPa.

The new ultra steel was used in the production of the new Infiniti Q50, which went on sale in the United States this year.

Prior to the development of the technology of the production of metal rolling with a strength of the strength of more than 1.2 GPa, it was extremely difficult to use steel as a material for autodulas of complex configurations. Today, Nissan received high -strength steel with good plasticity and an acceptable stretching limit. The ultra high -strength steel of 1.2 GPA allows you to make parts of a complex shape, stamps perfectly and is well welded, which provides it with widespread use in the production of vehicles.

The company's management adopted the concept of reducing the weight of new cars by 15% by 2017 and intends to achieve the goal, using new materials and design solutions.

The ambitious program Nissan called Nissan Green Program 2016 involves in the near future to achieve thirty -five percent increase in fuel economy compared to 2005. In this regard, the use of advanced developments in the production of steel will allow the campaign to reduce the total weight of the car and reduce fuel consumption.


1 - the prediction of the proceeds is a mechanical stress, above which the material is destroyed. According to GOST 1497-84, a more correct term is “temporary resistance to destruction”, that is, a voltage corresponding to the greatest effort, preceding the rupture of the sample during (static) mechanical tests. With a load corresponding to temporary resistance (or even exceeding it-in real and quasistatic trials) the destruction of the material (separation of the sample into several parts) will occur after some final period of time or instantly.
