New lightweight steel classes by NanoSteel could make GM cars lighter, faster and more fuel-efficient,
Today, one of the best ways to make cars lighter and quicker is carbon fiber, an extremely strong and light fiber-reinforced polymer that works well when used to sculpt out vehicle bodies instead of traditional steel. However, automobiles of the future could very well resort to the use of a new lightweight steel developed by NanoSteel. Sporting the strength and ductility required for automobiles, these three new classes of steel are comparatively lightweight and boast tensile strengths of 950 MPa, 1,200 MPa and 1,600 MPa and elongation performance of 35, 30 and 15 percent and are significantly less expensive to process! Also, GM Ventures, a General Motors subsidiary, has considered the use of these alloys in the making of cars that could very well lead to decrease curb weights, better fuel efficiency and higher speeds.
