The invention relates to a press-hardened sheet metal molded part (100), in particular a column reinforcement for a motor vehicle body, having different sheet metal thicknesses and strengths, having a first region (130) which is not hardened or only slightly hardened and a second region (110) which is press-hardened, the second region (110) has a greater or less sheet thickness than the first region (130). A transition region (140) is formed between the first region (130) and the second region (110), said transition region starting from the first region (130) having a sheet thickness transition region (141), an intermediate region (142) and a strength transition region (143).
本发明涉及一种加压淬火的板材成型件(100)、尤其是一种用于机动车车身的柱增强件,其具有不同的板材厚度和强度,其具有未硬化的或仅少许硬化的第一区域(130)和加压淬火的第二区域(110),所述第二区域(110)具有比所述第一区域(130)更大或更小的板材厚度。在所述第一区域(130)与所述第二区域(110)之间构造有过渡区域(140),所述过渡区域从所述第一区域(130)出发具有板材厚度过渡区(141)、中间区(142)和强度过渡区(143)。
