汽车传动轴用热轧钢带
Hot rolled steel strip for automobile transmission

主要用途
The main purpose

主要用于制作汽车传动轴管,由于传动轴管主要作用是支撑回转体、传递动力,故要求材料应具有:足够的强 度、刚度和一定的韧性以及较高的疲劳强度, 即要求原材料具有良好的综合力学性能。 制造汽车传动轴管一般采用直缝焊接工艺, 尺寸控制工艺采用通过控制外径来控制内径尺寸的方法,因此要求传动轴管用钢具有良好的焊接性能和高的尺寸精度。

Automobile transmission shaft tube steel is mainly used to make automobile drive shaft tube. As the main function of the transmission shaft tube is to support revolving body and transmit power, the material should be provided with: sufficient strength, stiffness and a certain degree of toughness as well as higher fatigue strength, that is, the raw materials should be provided with good comprehensive mechanical properties. The longitudinal welding technology is generally used to manufacture the automobile transmission shaft tube, and the dimension control process is based on the method of controlling the inner diameter by controlling the outer diameter; Therefore, the steel for the shaft tube of the transmission shaft should be provided with good welding performance and high dimensional precision.
