越来越多的人要求大幅提高新车的安全性，这就要求在其他重要的相关方面中，白色车身采用高强度材料。像22MnB5这样的可淬火锰硼合金钢具有卓越的强度值，复杂的形状和更高的精度。在所谓的跌落试验台上，对处于不同退火状态的试样进行变形，然后根据吸收能量、最大变形量和起皱行为等方面进行判断，以评价其碰撞适宜性。微观分析补充了对坠机适当性的评估。
The increasing call for significant safety improvements of new cars requires, among other important relevant aspects, the application of high strength materials for the body in white. Quenchable manganese boron alloyed steels like 22MnB5 offer superior strength values, complex shapes and enhanced accuracy. For the evaluation of the crash appropriateness specimens in different annealed states are deformed in a so called drop test bench and hereupon judged in terms of absorbed energy, maximum deformation and other aspects like wrinkling behaviour. Microscopic analysis complements the evaluation of crash-appropriateness.
