  • HOT FORMABLE, AIR HARDENABLE, WELDABLE, STEEL SHEET
    Publication number: 20180105892
    Abstract: A steel sheet comprising, in wt %, 0.04?C?0.30, 0.5?Mn?4, 0?Cr?4, 2.7?Mn+Cr?5, 0.003?Nb?0.1 0.015?Al?0.1 and 0.05?Si?1.0, has a chemistry that makes hot formed sheet after austenization insensitive to cooling rate and ensures a uniform distribution of tensile strength, in the range of 800-1400 MPa, across parts independent of the time delay between operations and final cooling/quenching. As a result, a formed part can be cooled while inside a die or in air. The addition of Nb reduces the amount of C needed to achieve a given tensile strength and improves weldability.
    Type: Application
