The recent years have seen a rising concern over energy resources, environmental protection and safety. With manufacturers placing more stringent requirements on automotive steel, OEMs demanding greater body weight reduction and longer service life, and automakers in increasingly urgent need of automotive UHSS, the whole auto manufacturing industry is embracing a development trend of lighter, safer, stronger and more energy-efficient and environmental-friendly automobiles. Automotive steel becomes the number 1 strategic product of both domestic and international steel makers, and hot-stamping steel in particular, owing to its excellent formability, supreme post-stamping strength and low cost, becomes the first choice of ultra-high strength materials for automakers. Furthermore, the upgrading of safety regulations on automobiles, such as introducing 25% small overlap crash test in C-IASI, and adopting more stringent side impact requirements in the 2018 version of C-NCAP, also helps make hot stamping the best option for automakers to achieve lighter body weight while improving automobile safety.
As the No.1 steel solutions provider in China, Valin ArcelorMittal Automotive Steel Co., Ltd. (VAMA) offers premium automotive steel solutions for automakers in China. With advanced technologies, VAMA provides high-end steel with smoother coating that is safer, cost-efficient and lighter, meeting the growing demand for lighter automotive steel in China and leading the sustainable development of the automotive steel industry. The China Automotive Material Website now has the privilege to invite Mr. Li Xiang, VAMA’s CTO, to share with us his thoughts on the application and development trend of hot-stamping AHSS Technology.
The new generation Al–Si coated hot stamping steel
In the over 200 years of steel being the main material to build a car, steel has been evolved for many times. The steel we see today is quite different from even 10 years ago. And steel has been proven to be the most efficient solutions in terms of weight reduction, safety increase and this in the most cost-efficient method which is also crucial for our clients that are operating in a fierce competitive environment. The pressure to reduce the fuel consumption and to meet stricter safety requirements is making more and more car makers to adjust their product development to advanced strength steel grades that are lighter and stronger, the increasing use of hot stamping steel is a good example of this trend where we can see the market increasing rapidly of the next years.
VAMA has introduced ArcelorMittal's new generation of aluminum-silicon coated hot stamping steel Usibor®2000 and Ductibor®1000, which are at the top level in the hot stamping steel market. The aluminium-silicon coated advanced high strength steel (AHSS), Usibor® 2000 is more than 30 percent stronger than the current most strong material used in car body design. And it could typically bring 10 to 15 percent weight savings when compared to existing hot stamping solutions, which will become available to the Chinese car industry allowing further weight savings and safety increase. We see that this material will be introduced in several new cars coming to the market in the next coming years replacing the currently used high strength steels, Mr. Li Xiang said.
Next to Usibor®2000, VAMA has also developed another hot stamping steel Ducibor®1000, which is a steel grade having less strength than the Usibor®2000 but shows an excellent crash ductility behavior and energy absorbtion. This steel grade in combination with Usibor®2000 allows for smart designs in which both steel grades are combined in one part, assuring strength and ductility in the right areas of the part: such as a B-pillar have a ductile zone in the lower area with Ductibor®1000 and a strong upper area with Usibor®2000 will allow to absorb energy in the lower zone in which deformation is allowed without impacting the passengers and have a strong upper area to avoid intrusion in that area causing impacts on the passengers. Now, VAMA had developed and realized Usibor®2000 and Ducibor®1000 mass production already.
The right material in the right place
Benefit from the technology transfer and support from ArcelorMittal, VAMA brings the cutting-edge technology to China, delivers the leading comprehensive steel solution to the market with the unique AHSS, UHSS and PHS steel like Usibor® and Ductibor® and DP 980 and and CP1000 and DP 1180 and full range of steel capacities.
VAMA is developing a special surface quality steels Ultragal® in mass production which can be used on outer panels such as doors and hoods, this will allow car makers to produce cars that have higher surface finishing and increased guarantees regarding corrosion protection, and provide more effective process solutions to customers, Mr. Li Xiang said.
To use the right steel in the right place, VAMA has also been promoting the innovation solutions from the very beginning of the lifecycle of a car. VAMA can provide multiple outstanding solutions with added value to car makers like light-weight solution of BIW, door ring, front module, rear module, hot stamping steel for car structure and battery pack, save the R&D time and the development cost for them.
When Usibor® and Ductibor® are combined into a single laser welded blank (LWB), the properties of a part can be tailored to achieve additional cost-effective and lightweight solutions. For example, ArcelorMittal’s S-in motion® projects for mid-size sedans and SUVs, which utilizes the hot stamping steel and LWB technology, have shown that weight savings of up to 26% are achievable for the body-in-white (BIW) compared to existing grades. The compatibility and consistency of new PHS materials and processes transferred from ArcelorMittal can ensure to meet the requirements of cost effective and high performance when using the materials.
Hot stamping has become very important to the automotive industry as a way of meeting specific crash-performance criteria and ensuring low overall weight at an affordable cost, and hot stamping steel is also developing in a lighter and stronger trend. As hot stamping steel have high strength, which is up to 2000 Mpa, automakers use the process to produce structural automotive parts such as: B-pillars; bumpers; sills; and cross members.
In the field of hot stamping steel, there are many steel grades and different technical specifications. By providing high-quality automotive steel products in great market demand with high-tech means, VAMA has become a leader in supplying hot stamping steel grades in China. For special processes like hot stamping, the core process parameters in the whole production of automotive steel are critical. We have some patents to protect the intellectual property rights of our technical invention and know-how, and ensure the product performance is guaranteed throughout the process. Parts made of steel must meet the requirements for the mechanical strength and be suitable for the subsequent coating and welding. If something goes wrong in the processing window or during the processing, the products may be substandard and fail to meet the demand of OEMs. Relying on the technical strength of global R&D center of ArcelorMittal, VAMA has gained valuable experience. By combing the experience and first-class production equipment, VAMA is able to provide high-performance products.
VAMA steel solutions for new energy vehicles
Besides, Mr. Li Xiang believes that Steel will keep on playing a huge role in the mobility of the road. Even going to electrification, a lot of EVs are concerned about weight savings on the one hand, on the other hand the cost-efficiency. Battery cases, as an example of an application solution, used in electric vehicles are mainly made of aluminum in some solutions. In this field, we have provided an innovative steel battery pack solution, which weighs basically the same with the aluminum one, but have greater impact resistance and costs less. Such a technical solution is also attractive to customers.
VAMA is more than a material supplier, we are solution provider. We have been developing several steel solutions consider the safety and weight requirements which are dedicated to the NEV market. Solutions have been developed for instance to display the advantage of using steel for battery boxes compared to alternative materials such as aluminum. With steel battery box, it will have better performance on safety as well as light weight. This solution is customized according to our customer’s design needs. We also see the solutions for different models, like front structure, rear structure, we benchmark the car models on the market, and optimize it into comprehensive solutions for NEV. VAMA has seen a very prosperous development since SOP in 2014. Thanks to the support from ArcelorMittal and Valin Steel, VAMA’s products had been finalized approval process at all major OEMs in China, these approval processes are now leading to more and more stable business. VAMA sets up offices in Shanghai, Beijing, Guangzhou, Chongqing, Changchun, Wuhan and Changsha, where the major automotive industry clusters are located, to shorten the response time of business and technical services to meet customer needs quickly.
