Nissan increases high-tensile steel strength to 1.2GPa

摘要

Nissan will use ultra-high-tensile strength steel rated at L2GPa in production vehicles from 2013. The OEM will use the new material as steel plates in cold pressed structural body parts -centre pillar reinforcements, front and side-roof rails and other key structural components. It should help to reduce vehicle weight by as much as 15kg. The carmaker said: "By adopting the new material in various parts of the vehicle, Nissan's new 1.2GPa Ultra High Tensile Strength Steel with high formability will contribute significantly to overall vehicle weight savings without adding the extra cost required by other lightweight materials, such as aluminium." The OEM developed the high-strength steel in collaboration with Nippon Steel Corporation and Kobe Steel.
