    Nippon Steel & Sumitomo Metal Corp. has developed a new automotive steel that is 20-30 percent lighter and 25 percent stronger than any high-tensile steel now on the market.

    The highest tensile strength currently available is 1400 megapascals with the industry average around 1200 MPa. NSSMC’s new steel has a grade of 1470 MPa and is designed for use in vehicle frames, chassis and other components where strength and light weight are critical.
