ArcelorMittal develops automotive steel products to optimise the weight and cost of vehicles, reduce carbon emissions and ensure high standards of safety


ArcelorMittal supports car manufacturers through the different stages of a vehicle’s lifecycle

ArcelorMittal is a technology leader in advanced high-strength, galvanised and coated steels – products that are used in the manufacturing of cars, vans and trucks.

About one fifth of global car production is made from ArcelorMittal steel, while 20% of the company's revenues for 2016 were contributed by its automotive business.

With an industrial presence in 18 countries across four continents, and sales and service offices worldwide, ArcelorMittal is uniquely positioned to supply global automotive customers with the same products worldwide. 

More than one third of our investment in product research and development (R&D) is allocated to the automotive industry, and we have six laboratories that are dedicated fully, or partly, to R&D for the automotive market in East Chicago in the US; Hamilton in Canada; Maizières, Montataire and Gandrange in France;and Tubarão in Brazil. Our R&D engineers work with carmakers throughout the lifecycle of their products to develop automotive steels that are stronger yet lighter than existing materials. We also develop new, cost-effective coatings to improve corrosion resistance, paint appearance and application processes.

Our presence in different regions also gives us valuable insight into new market trends. For example, ArcelorMittal provides steel solutions for low-cost cars and engine powertrains to meet changing customer and market needs. Our automotive steel solutions cover all metallurgical ‘families’ of steels – distinguished by their different properties and compositions.

We anticipate that regulatory and customer expectations for lightweight cars will rise in the future. Working closely with our automotive partners, we have developed S-in motion, a set of automotive steel solutions to make cars lighter – without compromising safety – and, in turn, reduce their carbon emissions.

With our current catalogue of automotive products, we support carmakers in optimising weight and cost, while reducing carbon emissions and, crucially, ensuring that stringent safety standards are met.

ArcelorMittal is a leading producer of laser-welded blanks and has a specialised business unit for tailored blanks – a manufacturing technology that improves the performance of car parts in a vehicle. These tailored blanks, or laser-welded blanks, are made by welding together flat steel sheets of different thicknesses, grades and coatings for the optimal combination of strength and ductility. These products also reduce the weight and cost of vehicles, and improve safety by enhancing crash performance.
