  • Patent number: 11566306
    Abstract: The present invention relates to high-strength medium manganese steel for warm stamping, which contains 3-10 wt % of manganese (Mn), 0.05-0.3 wt % of carbon (C), and 0.1-1.0 wt % of silicon (Si) as components thereof, with the balance being iron (Fe) and unavoidably contained impurities. The present invention performs heat treatment at the low austenitizing temperature of medium manganese steel, and thus has the effect of reducing the high thermal energy consumption of the prior art hot stamping process. Furthermore, the present invention does not require an additional temperature process, and can obtain high strength by only slow cooling such as air cooling outside a mold without performing cooling at high rate inside the mold, and thus has the effects of simplifying a process and improving manufacturing efficiency.
