为做到即能使汽车轻量化又可提高撞击时车本身的安全性能,就需要使制造汽车零部件用钢板的高强度化,而且使用高强度钢板制造汽车零部件的部位正呈扩大化趋势。最近,使用980MPa级别超高强度钢板的实例也越来越多。众所周知,钢板的强度越高其易加工性能越低,因此,有必要根据汽车不同部位部件的使用要求分别赋予其特性。为便于管理,对980MPa级别超高强度钢板按重视整体延伸率型、重视局部延伸率型以及兼顾两者平衡的均衡型进行了菜单化处理。本文将对每种类型钢板的特征及其所适用的部件实例做一下介绍。
In order to make the vehicle lighter and to improve the safety performance of the vehicle itself at the time of impact, it is necessary to increase the strength of the steel sheet for the manufacture of automobile parts and to enlarge the production of automobile parts using high-strength steel sheets . Recently, there have also been more and more examples of the use of 980 MPa grade ultra-high strength steel sheets. As we all know, the higher the strength of the steel, the lower the machinability, therefore, it is necessary according to the different parts of the car’s use of the requirements were given their characteristics. For ease of management, 980MPa-class ultra-high strength steel plate according to the overall extension rate, emphasis on the local extension of the balance of the balance between both types of menu processing. This article will introduce the characteristics of each type of steel plate and the applicable parts examples.
