If you’ve never heard of Advanced High Tensile Strength Steel (AHSS), that’s okay. We’re here to explain it to you. Nissan Motor Co. just announced that it plans to use a whole lot more AHSS in up to 25 percent of the vehicle parts installed in its new production models. To help reduce vehicle weight, this will go into effect in 2017.
Nissan has developed Ultra High Tensile Strength Steel with High Formability-also known as 1.2 GPa- and has installed it in the new Infiniti Q50, which goes on sale in North America in 2013. Prior to the development of 1.2 GPa, high strength steel has been difficult to use for vehicle parts with complex shapes. Nissan continues to be the only auto manufacturer using 1.2 GPa. It provides greater elongation and offers strength and high formability. Now it can be used for complex shaped parts, which have been near impossible in the past.
In addition, employing 1.2 GPa high tensile strength steel leads to fewer materials used per vehicle produced, and existing production lines can be used without a big modification. This results in a reduction in total cost per unit, reduced weight and better fuel economy. This is part of Nissan’s Green Program 2016.
