trends in steel usage in the automotive industry

Steel has long been the preferred material for global automakers.
The use of steel enables automakers to meet the required strength and safety standards for their vehicles at a relatively low costa-
Other materials.
However, given the increasingly stringent regulations on vehicle emissions and fuel efficiency, reducing car weight has become an extremely important consideration for automakers.
As automakers want to reduce the weight of their vehicles in order to comply with these regulations, Steel faces increasing competition from aluminum and other materials.
In this article, we will look at the current trends in steel use in the automotive industry, changes in regulations, the impact on steel producers, and the measures taken by these companies to address these challenges.
According to the World Steel Association, steel use in the automotive industry accounts for about 12% of global steel consumption.
ArcelorMittal is one of the world\'s leading manufacturers of automotive steel, with about 16.
2014 accounted for 7% of the global automotive steel market.
Steel is the leading material for automobile manufacturing, accounting for about 60% of the average weight of the car.
However, as automakers want to comply with strict regulations on vehicle emissions and fuel efficiency, the share of steel in car manufacturing may decline.
Fuel efficiency and emission reduction regulations one of the most pressing areas of concern and strategic focus for automakers is to comply with changing automotive industry regulations.
In order to solve environmental problems, governments in North America and Europe have set specific targets for fuel efficiency and emission reduction.
For example, the United StatesS.
The government aims to increase the average fuel efficiency of cars from 27.
5 miles to 54 miles per gallon in 2012.
4 miles per gallon in 2025.
In the EU, the goal is to reduce the average vehicle emissions by 2015 from 130 grams per kilometer in 2021 to 95 grams per kilometer.
To make cars more fuel efficient, manufacturers have been looking for ways to make cars lighter.
This opens the door for other materials such as aluminum to erode the market share of steel.
Due to the need to make the car lighter, manufacturers have been adding more proportions of lighter materials such as aluminum and plastic composites to their cars.
Ford\'s iconic F-
150 pickup.
Aluminum about 25% F-of curb weight of 2015150.
While this is a concrete example, it also shows a bigger trend.
In North America, the average aluminum content of cars has increased by 44.
3 pounds vehicles per vehicle from 2012 to 2015, compared with 10 pounds vehicles per vehicle from 2010 to 2012.
This is equivalent to an increase in the contribution percentage of aluminum to the average curb weight of North American cars from 9% in 2012 to 10. 4% in 2015.
According to a global Ducker study, the average aluminum content of North American cars will increase to 19% of the weight of cars by 2025.
Since aluminum is a lighter metal than steel, the increase in the volume of aluminum used in the average car better reflects the increase in the range of metal applications.
The proportion of aluminum used in automobiles is expected to rise from 6.
6% from 2015 to 26. 6% in 2025.
In view of the good regulatory environment, the scope of use of aluminum as automotive manufacturing materials will definitely increase.
However, aluminum is a metal that is much more expensive than steel.
Similarly, other lighter materials such as manganese and plastic composites are also more expensive.
So there is a trade
Between reducing weight and increasing costs.
This is an opportunity for new materials that balance low cost and reduce weight.
This is an opportunity for steelmakers to try to exploit their advanced high-strength steel.
State-of-the-art high-strength steel companies such as ancelormittal and American steel giantsS.
Steel companies are investing heavily in the production of advanced high-tech products.
In order to maintain the position of steel as the preferred material for the automotive industry, strength steel.
The minimum tensile strength of advanced high strength steel is 500 to 800 MW (MPa).
Compared with traditional steel with the same strength, these steel can significantly reduce the weight.
These materials are competitive compared to other materials, as shown in the following figure :(

Companies such as ancelormittal are working with OEMs (OEMs)
To develop steel solutions that meet the manufacturer\'s requirements in terms of weight reduction and safety.
A proprietary, dynamic approach to the success paradigm of Miluo-Mittal, provides a typical C-19% weight reduction-Segment vehicle.
In addition, the company has introduced other categories of advanced high-strength steel, such as proprietary Usibor and Fortiform series steel, which are specially tailored for automotive applications.
30% of ArcelorMittal\'s R & D budget is used to develop solutions for the automotive market. Similarly, U. S.
Steel\'s proprietary double ten and travel range steel is also targeted at the automotive industry.
This investment by steel companies will help to maintain the competitive power of steel to a certain extent. a-
