Reducing the weight of new cars in order to deliver better fuel economy is a major focus for automakers worldwide. This focus extends to the chassis system where engineers are striving for lower weight solutions capable of meeting stringent safety and environmental requirements. To meet these goals, engineers need new materials featuring high specific strength and fatigue resistance, together with the manufacturability that enables them to innovate.
The new hot-rolled XPF family of steels promises a major breakthrough in automotive structural materials technology. It addresses the known challenges of current high-strength steels in terms of forming and manufacturing by combining the mechanical strength and fatigue resistance that designers require, with a formability that provide seven greater freedom to reduce vehicle weight without compromising manufacturing robustness or safety standards.
