Lightweight high-strength wear-resistant steel plates drive the future of the automotive market
Japan JFE wear-resistant steel research team once predicted that lightweight wear-resistant steel will become the main material of the future automotive industry The team designed a new wear-resistant steel, by reducing the weight of the wear-resistant steel plate, while maintaining the strength of the wear-resistant steel plate, can significantly improve vehicle fuel efficiency by 15%, passenger driving safety assurance can also be improved.
With the rapid development of the automobile industry, some new production quality standards will gradually become a reality in the future, at present, the world's six top automobile manufacturers such as Mercedes-Benz are making revolutionary new attempts.
Car manufacturers generally use lightweight metals such as aluminum instead of relatively heavy wear-resistant steel as body materials. However, blindly increasing the content of aluminum in steel will lead to the formation of intercrystalline compounds, which is unfavorable to the quality of wear-resistant steel plates, and may cause wear-resistant steel plates to break more easily. The new steel designed by JFE will increase its strength by 50% while being lightweight and less likely to break compared to other lightweight materials. The use of lightweight wear-resistant steel plates has also made it possible for car manufacturers to introduce other new technologies into vehicle production.
In the automobile lightweight movement, small cars not only need to improve strength, but more importantly, they must reduce weight. JFE's products are receiving more and more attention, and its new steel production cost is one-tenth of the total use of titanium alloy, and the quality of automobiles is reduced by 15%.
In addition, the necessary measures for the development of electric vehicles also include reducing weight, which also provides a good opportunity for lightweight wear-resistant steel plates.
