Advanced high-strength steels have been widely used to improve the crashworthiness and lightweight of vehicles. Different from the popular cold stamping, hot forming of boron-alloyed manganese steels, such as 22MnB5, could produce ultra-high-strength steel parts without springback and with accurate control of dimensions. Moreover, hot-formed medium-Mn steels could have many advantages, including better mechanical properties and lower production cost, over hot-formed 22MnB5. This paper reviews the hot forming process in the automotive industry, hot-formed steel grades, and medium-Mn steel grades and their application in hot forming in depth. In particular, the adaptabilities of medium-Mn steels and the presently popular 22MnB5 into hot forming were compared thoroughly. Future research should focus on the technological issues encountered in hot forming of medium-Mn steels to promote their commercialization.

汽车工业中用于热成型的中锰钢

先进的高强度钢已被广泛用于改善车辆的耐撞性和轻量化。与流行的冷冲压不同,硼合金锰钢(如22MnB5)的热成型可以生产超高强度钢零件,而不会回弹并且尺寸控制准确。而且,与热成型的22MnB5相比,热成型的中锰钢具有许多优点,包括更好的机械性能和更低的生产成本。本文深入探讨了汽车行业的热成型工艺,热成型钢种和中锰钢种及其在热成型中的应用。特别是,对中锰钢和目前流行的22MnB5在热成型中的适应性进行了比较。
