汽车传动部件由于形状复杂、壁厚,一直采用铸造法生产。为了减轻此类部件的重量和降低生产成本,一些厂家采用钢板冲压工艺。但由于加工问题,汽车传动部件冲压成形钢板只局限于抗拉强度<600MPa级。日本神户制铜公司制成1种新型的高强度热轧钢板,成功地实现了抗拉强度>600MPa的汽车传动部件的冲压成形。这种钢板加入了如下元素:1.02%的铜、1.01%的
Automotive transmission parts due to the complexity of the shape, wall thickness, has been the casting method of production. In order to reduce the weight of such parts and reduce production costs, some manufacturers use steel stamping process. However, due to processing problems, automotive transmission parts stamping forming plate is limited to tensile strength <600MPa level. KOBE Japan made a new type of high-strength hot-rolled steel plate, successfully achieved the tensile strength> 600MPa automotive transmission parts stamping. The plate incorporates the following elements: 1.02% copper, 1.01%
