汽車懸掛中的一種輔助彈性元件,可防止車身在轉彎時發生過大的橫向側傾,從而達到防止汽車橫向傾翻和改善平順性的目的。
34MnB5汽車穩定桿汽車穩定桿用鋼,碳含量更高,在提升空心穩定桿強度的同時,便于進一步實現汽車輕量化。
我公司緊跟汽車發展趨勢開發新鋼種,了解到歐洲汽車穩定桿用鋼正逐步由34MnB5向高精尖的40MnB5轉化,而國內尚屬空白,聯合某知名汽車零部件企業開展34MnB5汽車穩定桿高級別穩定桿用鋼40MnB5的研發。
我公司研發技術團隊34MnB5汽車穩定桿克服沒有國外材料做對照、技術內容封鎖的不利條件,憑借在26MnB5和34MnB5汽車穩定桿用鋼生產中的技術積累,摸索出40MnB5的生產工藝,歷時近3個月時間,完成了40MnB5研發。產品的物理性能、表面質量、焊接性能等良好,受到客戶認可。
目前,我公司26MnB5、34MnB5、40MnB5汽車穩定桿用鋼已經全面投入市場,滿足汽車行業不斷升級的市場需求,助力車輛實現輕量化。
These steel grades belong according to DIN EN ISO 683-2 to the product category of quenched & tempered steels, and features outstanding forming properties in the soft delivery state and high strength after heat treatment (hardening). The materials strength is propagated by adding a small fraction of boron to the carbon, manganese and chromium composition. Currently, Salzgitter Flachstahl can supply manganese-boron Steels of 10MnB5 to 46MnB5 and customer-specific analysis variants by arrangement.
This steel grade is available as hot rolled coil (pickled, unpickled) in nominal thicknesses of 2.0 to 12.70 mm and in widths according to the Salzgitter Flachstahl delivery program.
Range of chemical composition guaranteed
(differing ranges by prior Agreement)
These boron-alloyed quenched and tempered steel grades in hot rolled state usually have a ferritic-pearlitic microstructure with a typical grain size of > 9 according to DIN EN ISO 643.
Thanks to the combination of formability and temperability, the automotive industry takes advantage of these steel grades especially for the production of supporting body parts (motor vehicles) and other safety-relevant components. Examples are the B-pillar, side impact protection, chassis components or bumpers.
Within the automotive industry, welded precision tubes made of these steel grades are, for instance, used to make stabilizers, axle driving or gearbox shaft and other parts relevant to passive security. Another application field for them is the production of boiler tubes.
