CHICAGO Nissan Motor Co.
Ltd. plans to expand its use of advanced high-strength steels
(AHSS) starting in 2017 as part of an initiative to reduce
vehicle weight by 15 percent, it said.
The Yokohama, Japan-based
automaker ultimately plans to use AHSS in up to 25 percent of
its vehicle parts.
Nissan has already developed an
ultra-high-strength steel (UHSS) with high formability for use
in the new Infiniti Q50, which will go on sale in North America
The company claims that it is
the only automaker using 1.2-gigapascal UHSS with high
formability, which is necessary for forming complex parts.
Employing AHSS and UHSS will reduce the automakers
total cost per vehicle by cutting the amount of material used,
the company said. In addition, production lines can be adapted
for AHSS and UHSS use without requiring major modifications
