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
will include the hot stamping steel grades, Usibor 1500 and
Ductibor 500. It is steel technology that has been used in
the past by international car makers and VAMA’s aim is
to ensure that these solutions are now available locally in
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.

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
more stringent, OEM design centres in China are working quickly to make the next generation of cars safer and lighter.ArcelorMittal works with these design centres, bringing its expertise to the efforts on weight reduction, crash protection and the other aspects where steel technologies assist.
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.
