隨著人們生活水平的提高,人們對(duì)于生活質(zhì)量的要求也不斷的提高,當(dāng)晚上我們小區(qū)外的馬路上停滿了汽車,由此看來(lái)汽車日漸成為人們的代步工具,今天小編給大家介紹的可不是汽車,而是汽車身上的一個(gè)零件,當(dāng)然汽車通常由幾千個(gè)零件組成,現(xiàn)代高級(jí)矯車由幾萬(wàn)個(gè)零部件組成，為滿足汽車節(jié)能、環(huán)保、安全、舒適的要求,實(shí)現(xiàn)輕量化、高強(qiáng)度、高性能的目標(biāo),構(gòu)成汽車的材料也發(fā)生了巨大的變化。
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.
從前的高強(qiáng)度鋼板,拉延強(qiáng)度雖高于低碳鋼板,但延伸率只有后者的50%,故只適用于形狀簡(jiǎn)單、延伸深度不大的零件?，F(xiàn)在的高強(qiáng)度鋼板是在低碳鋼內(nèi)加入適當(dāng)?shù)奈⒘吭?經(jīng)各種處理軋制而成,其抗拉強(qiáng)度高達(dá)420N/mm2,是普通低碳鋼板的2~3倍,深拉延性能極好,可軋制成很薄的鋼板,是車身輕量化的重要材料。主要有含磷冷軋鋼板、烘烤硬化冷軋鋼板、冷軋雙相鋼板和高強(qiáng)度IF冷軋鋼等,車身設(shè)計(jì)師可根據(jù)板制零件受力情況和形狀復(fù)雜程度來(lái)選擇鋼板品種。
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.
含磷高強(qiáng)度冷軋鋼板:含磷高強(qiáng)度冷軋鋼板主要用于轎車外板、車門、頂蓋和行李箱蓋升板,也可用于載貨汽車駕駛室的沖壓件。主要特點(diǎn)為:具有較高強(qiáng)度,比普通 冷軋鋼板高15%~25%;良好的強(qiáng)度和塑性平衡,即隨著強(qiáng)度的增加,伸長(zhǎng)率和應(yīng)變硬化指數(shù)下降甚微;具有良好的耐腐蝕性,比普通冷軋鋼板提高20%;具有良好的點(diǎn)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.
