The strength of steel determines the structural properties of the car's body, which is the driving force behind the steel industry's continuous development and innovation, and the discovery of the amazing potential of steel materials. World Auto Steel and its members are dedicating to promote the application of advanced high-strength steels (AHSS) in the automotive industry. Their project team launched a campaign called Steel Your World in September 2017. The event invited the global automotive community to participate in the video shooting, that guests from different perspectives introduced the steel especially AHSS to the public, to open a window for car design.
Thinner, stronger, safer
For decades, the steel industry has pioneered a whole new class of materials that are 50% stronger than their predecessors. At the core of this innovation lies the ever-growing AHSS family. No other automotive material compares to the variety of steel strength levels today.
This means that the steel can be made thinner, yet retain its strength for vehicle structure performance and safety. Thinner material means less material is used, and therefore components are lighter, contributing to vehicle weight reduction and reduced environmental emissions. Because primary manufacture of steel produces fewer emissions than any other automotive material, it’s a win-win, both in terms of reduced steel manufacturing and vehicle emissions.
These AHSS capabilities result from their unique combination of strength and ductility. AHSS are complex, sophisticated materials, with carefully selected chemical compositions and multiphase microstructures resulting from precisely controlled heating and cooling processes. Various strengthening mechanisms are employed to achieve a range of strength, ductility, toughness, and fatigue properties.
How carmakers use AHSS
From March 27th to 28th, VAMA was presented as a competitive lightweight material supplier in the 5th New Energy Vehicles International Forum. VAMA CMO Jurgen Cobbaut and GONVVAMA CTO Yannick Yin gave speeches on the theme of lightweight and safe automotive structures in the forum.
In terms of anti-collision performance, processing technology and cost, advanced high-strength steel has obvious advantages over other materials and can meet the dual needs of reducing vehicle quality and improving crash safety performance.
With the support of the ArcelorMittal Global R&D Center and the EVI team, VAMA collaborates with domestic automotive OEMs to design and develop next-generation models that include new energy vehicles. While reducing the existing vehicle design costs, it achieves a 15% weight reduction goal for white body.
At present, VAMA steel solutions have been applied to white body of new energy vehicles, and integrated door knockers, battery packs, and front and rear frames. The new generation of advanced high-strength steel product Usibor® 2000 with aluminum-silicon coating will be launched in the domestic market in this year. Compared with the Usibor® 1500, which is currently widely used in OEMs. The strength of Usibor® 2000 increases by more than 30% to a maximum of 2000 MPa. And could be loss 10% to 15% weight.
VAMA and GONVVAMA have just completed the exhibition of advanced automotive steel solutions at the 2018 International Advanced Automotive Manufacturing Technology Conference and Exhibition (March 22-24, Wuhan). Exhibited a application examples of world’s leading automotive steels and hot stamping high-strength steel materials for automotive manufacturers in the Midwest , which attracted OEMs from DFI, BYD, Great Wall, Chery Jaguar Land Rover, etc. and Tier one parts suppliers to visit and consult.
CP1000 is an advanced high strength complex phase steel for automobile with over 1000MPa tensile strength. It is widely used in car body manufacturing, such as safety parts and structural parts like bumper beam, seat track, etc. It can effectively and efficiently reduce weight, therefore reduce energy consumption and pollution, improve material efficiency, and safety performance at the same time.
Although the composition systems of complex phase steel and dual phase steel are similar, complex phase steel has more complex microstructure and higher requirement for technology and equipment. Only a few steel mills in China have the production capability at present. Thanks to its sophisticated metallurgical structure and low carbon content, complex phase steels enjoy a higher yield ratio, better bending, hole expansion and flanging ability, and excellent welding performance.
With first-class production equipment, VAMA adopts the leading technology of ArcelorMittal, successfully developed the qualified CP1000 on its continuous annealing line. Through VAMA’s special process route, the CP1000 shows qualified microstructure, stable performance, excellent surface quality, and meets the material certification requirements of its customers.
With the leading technologies, VAMA has the capability of CP1000 mass production and becomes one of the steel mills that has this capability. Along with the increasing proportion of high-strength steel in BIW, complex phase steel – an important member of the high-strength steel family will continue to contribute to achieve the lightweight, safety and green goals of China's automotive industry.

Just after the Slight Cold (23rd Solar Term), from Jan. 3 to 6, 2018, ValinArcelorMittal Automobile Steel Co., Ltd (VAMA) and Loudi Economic & Technical Development Zone organized 47 volunteers to launch the natural gas safe use voluntary service for 11 residential communities including Loudi Gangdu Garden, Xianren’ge and Chunhe Garden etc., in order to improve residents’ awareness of safe use of the natural gas. Volunteers explained and publicized cautions of safe use of the natural gas for residents, including the danger of non-standard uses of gas and their corrections, and they also conducted indoor examination for 53 families, checked whether any hidden danger of gas leakage of the natural gas pipelines and explained the daily safe use and the method of self-detection on site. Volunteers had brought warmth and safety to residents of these communities.
6 Cautions for Safe Gas Use
Volunteers are divided into 6 groups and separately visited 11 communities. They distributed a total of 10,000 materials about safety to community residents and focused on popularizing the 6 cautions for safe use of the natural gas among residents:
3 Measures to Detect Gas Leakage
From Jan. 3 to 5, VAMA Health and Safe Production Center organized the special examination of gas safety against the natural gas station of the production area, the acid regeneration calciner and high-pressure natural gas station of the dining hall and conducted overall examination and one-on-one safety presentation for 31 families living in neighboring 11 residential communities. On Jan. 6, divided into 6 groups, 14 volunteers of VAMA natural gas safety team provided the indoor natural gas examination service for natural gas users of the community for free with the “secret tool”, identified on site the hidden danger for a total of 22 families in 9 residential communities and summarized and reported the investigation results to Huarun Gas Company for correction. At the same time, they showed gas users how to check the gas leakage in daily life, including smelling and reading the alarm, identification by soap water and reading the gas meter etc.
To VAMA, safe production and safe living are placed above all else. It is the responsibility for each company of the park to construct a safe community. The natural gas safety promotion campaign this time aimed to improve residents’ awareness of safe use of natural gas, popularize the basic measures for safety precautions, prevent the accident from occurring and build a safe production park and safe living community jointly with all others.

The global automotive manufacturing industry operates within a busy regulatory environment. This is certainly the case here in China. Things are moving very quickly, with a regulation framework that is becoming more stringent and demanding. So the challenge for suppliers is not only to match the regulation but to do so within the very short timescales set by the authorities.
There are two main aspects. One is to drastically improve fuel efficiency in China’s car fleet, with the target to reach an average consumption of no more than 5 litres per 100 kilometres by 2020. A further target of a maximum of 4.5 litre per 100 kilometre is anticipated for the period after.On emission standards, China wants to achieve a Euro 6 equivalent by 2020.
Then comes safety regulations. It is very likely that new crash management standards will be in place in China by next year, raising the requirements here to match those of the US.
A further issue to consider is supply chain reform. The government wants to see China’s industry move from pure manufacturing base to one with more high technology content, and that there be greater domestic ownership of the key developments that are driving the industry.
The latter particularly resonates with China’s domestic car makers who are receiving a strong push and pull from the government to upgrade technology content in the products they are developing and selling domestically.
There is also an enormous impact on the supply side.China’s government wants to make sure that solutions and products are available locally to support its initiative.In other words, they want the automotive industry to strive for self-sufficiency in innovation and supply components rather than rely on the need to import.
In all of these aspects around innovation, advancement and supply, VAMA is ready to play a key role.
As a joint venture between ArcelorMittal and Valin Group,VAMA covers a full range of steels commonly used in car design. The ArcelorMittal-owned and patented family of steels start from mild steel grades and extends to steels that have very high strength limits, e.g. Dual Phase products DP980 and DP1180HY.
In addition, new product launches for the Chinese market
Over a relatively short period of time, hot stamping technology has forged a path with impressive speed into the Chinese market. It was first introduced by the international OEMs and has quickly been adopted by the domestic car makers over the past three or four years.
The situation now is that the number of hot stamping lines in China is equivalent to that of the rest of the world combined.
VAMA has been developing new steel grades in this hot stamping family. The Usibor 2000 steel grade is a new and even stronger steel, due to come to market next year. It will assist OEMs reduce the weight of cars even further. From a
car that is, say, 300kg, Usibor 2000 can win back around 20-30kg, helping to meet environmental regulations but, as the grade is stronger, without jeopardising safety.
VAMA will be licensed to produce ArcelorMittal’s latest grades for hot stamping, Usibor 2000 and Ductibor 1000, for the Chinese market
Looking at other grades, Ductibor 1000 is being developed to combine high strength with high ductility helping OEMs produce parts with a complex shape. They can still use hot stamping technology and retain the high crash resistance and energy absorption qualities.
As one example, VAMA is working with OEMs on a door ring, a body side reinforcement made from hot stamped steel grades. VAMA is able to supply blanks, pre-welded, that the OEM’s press shop can stamp — in a single operation —to create the part.
In addition, VAMA and ArcelorMittal have been working on steel technologies for parts such as visible panels (boots,roofs, doors) where car makers require higher quality surface standards.
As a joint venture between ArcelorMittal and Valin Group, VAMA covers a full range of steels commonly used in car manufacturing
EV car production
The role of AHSS in EV production is becoming more and more important and these cars are a high priority in China.In 2020, China’s target is to produce two million electric cars; and to double that by 2025. Weight savings in this type of vehicle are crucial as the battery itself accounts for much of car’s overall weight.
Looking specifically at the requirements for electric vehicles, the battery and the battery cover also come with significant safety and crash protection considerations. There will be strong push to get AHSS into this type of car.
Meeting demand in China
As a major VAMA shareholder, ArcelorMittal offers great support on a technology level and VAMA will be licensed to manufacture the latest grades, Usibor 2000 and Ductibor 1000, for the Chinese market. ArcelorMittal also brings competence in co-engineering. As regulation becomes
VAMA’s other major shareholder is Hunan-based supplier Valin Group, which provides the primary material.Upgrades and technology transfer at the production facility means that VAMA can be sure that the base material it receives from Valin successfully matches the requirements and standards expected within the automotive industry.

ArcelorMittal Chairman and CEO, Mr. Mittal, was invited to participate the 5th Global CEO Council meeting with Premier Li at the Great Hall of the People on 7th Jun 2017. During the meeting, Mr. Mittal talked about ArcelorMittal has invested heavily in leading R&D centers, most advanced production facilities to meet high requirements of clients. Automotive steel is one such example where we are the leading supplier worldwide to automotive manufacturers.
ArcelorMittal has extended automotive steel franchise to China, with major production facility (VAMA, in partnership with Hunan Valin Group), in Hunan province, with investment of around $ 1bn. High strength light weight steel for automotive can make automotive industry more environmental friendly and enhance passenger safety.
VAMA is an example of supply side reform – whereby it takes hot rolled coils (which are in excess supply) and using high technology process to convert into high strength automotive steel (which are in short supply).
