随着人们生活水平的提高,人们对于生活质量的要求也不断的提高,当晚上我们小区外的马路上停满了汽车,由此看来汽车日渐成为人们的代步工具,今天小编给大家介绍的可不是汽车,而是汽车身上的一个零件,当然汽车通常由几千个零件组成,现代高级矫车由几万个零部件组成，为满足汽车节能、环保、安全、舒适的要求,实现轻量化、高强度、高性能的目标,构成汽车的材料也发生了巨大的变化。
With the improvement of living standards, people's requirements for the quality of life is improved constantly, when we plot the night on the road outside the parked car, the car was becoming a means of transport, today Xiaobian to introduce the car can not, but a part of steam on the body, usually of course cars by the thousands of parts of modern advanced car by tens of thousands of parts, in order to meet the needs of automobile energy saving and environmental protection, safety and comfort requirements, realize the lightweight, high strength and high performance target components of automotive materials has also undergone tremendous changes.

从前的高强度钢板,拉延强度虽高于低碳钢板,但延伸率只有后者的50%,故只适用于形状简单、延伸深度不大的零件。现在的高强度钢板是在低碳钢内加入适当的微量元素,经各种处理轧制而成,其抗拉强度高达420N/mm2,是普通低碳钢板的2~3倍,深拉延性能极好,可轧制成很薄的钢板,是车身轻量化的重要材料。主要有含磷冷轧钢板、烘烤硬化冷轧钢板、冷轧双相钢板和高强度IF冷轧钢等,车身设计师可根据板制零件受力情况和形状复杂程度来选择钢板品种。
In the past, the drawing strength of the high strength steel plate was higher than that of the low carbon steel plate, but the elongation rate was only 50% of that of the latter. Therefore, it was only suitable for the parts with simple shape and little extension depth. High strength steel is now adding trace elements properly in the low carbon steel, by various processing and rolling, the tensile strength is up to 420N/mm2, is 2~3 times that of ordinary low carbon steel, deep drawing can be rolled into excellent ductility, thin steel plate, is an important material for lightweight body. Mainly phosphorus cold rolled steel plate, bake hardened cold-rolled steel plate, cold-rolled dual phase steel plate and high-strength IF cold-rolled steel, etc., body designers can according to the parts of the plate force and shape complexity to select steel varieties.
含磷高强度冷轧钢板:含磷高强度冷轧钢板主要用于轿车外板、车门、顶盖和行李箱盖升板,也可用于载货汽车驾驶室的冲压件。主要特点为:具有较高强度,比普通 冷轧钢板高15%~25%;良好的强度和塑性平衡,即随着强度的增加,伸长率和应变硬化指数下降甚微;具有良好的耐腐蚀性,比普通冷轧钢板提高20%;具有良好的点焊性能。
High strength cold rolled steel sheet containing phosphorus: high strength cold-rolled steel sheet containing phosphorus is mainly used for car outer panel, door, top cover and trunk lid lifting plate. It can also be used for stamping parts of truck cab. Main features: high strength, high ratio of common cold rolled steel 15%~25%; excellent strength ductility balance, namely with the increase of strength, elongation and strain hardening index decreased little; has good corrosion resistance, 20% higher than the common cold rolled steel plate has good welding performance.
