    • In a method of making a shaped metal part for a motor vehicle component, a blank is made from a steel alloy containing, in weight percent: carbon (C) 0.18% to 0.3%, silicon (Si) 0.1% to 0.7%, manganese (Mn) 1.0% to 2.5%, phosphorus (P) maximal 0.025%, chromium (Cr) 0.1 to 0.8%, molybdenum (Mo) 0.1 to 0.5%, sulfur (S) maximal 0.01%, titanium (Ti) 0.02% to 0.05%, boron (B) 0.002% to 0.005%, aluminum (Al) 0.01% to 0.06%, balance iron and impurities resulting from smelting, The blank is heated to a temperature between 900° C. and 950° C., and formed in a press tool into a formed part which is quenched and tempered while still being in the press tool. At least one region of the formed part is then annealed to become soft by a heating operation within a time interval of less than 30 seconds to thereby provide the region with higher ductility.
    • 在制造机动车用部件的成形金属部件的方法中,坯料由钢合金制成,所述钢合金含有重量百分比:碳(C)0.18%〜0.3%,硅(Si)0.1%〜0.7%,锰 (Mn)1.0%〜2.5%,磷(P)最大0.025%,铬(Cr)0.1〜0.8%,钼(Mo)0.1〜0.5%,硫(S)最大0.01%,钛(Ti)0.02% 0.05%,硼(B)0.002%〜0.005%,铝(Al)0.01〜0.06%,铁和杂质产生的杂质,将坯料加热至900〜950℃, 在冲压工具中形成为在仍处于压制工具中的淬火和回火的成形部件。 然后通过在小于30秒的时间间隔内的加热操作将成形部件的至少一个区域退火以变软,从而为该区域提供更高的延展性。
