Market leader in steel

ArcelorMittal is the world’s largest steel producer. Steel shipments for the year ended December 31, 2015 totalled 84.6 million tonnes. We operate through four segments:

  • NAFTA (North American Free Trade Agreement area): the largest producer of steel in North America
  • ACIS (Africa and CIS region): the largest steel producer in Africa, a significant steel producer in the CIS region, with a growing presence in Asia, including investments in China and India
  • Brazil: the largest producer of steel in South America
  • Europe: the largest steel producer in the EU, with significant operations in France, Germany, Belgium, Spain, Luxembourg, Poland, the Czech Republic and Romania

Our broad range of products, together with our distribution network and research and development (R&D) programmes, enable us to build strong relationships with customers, which include many of the world’s major automotive and appliance manufacturers. We are also a strategic partner to several of the major original equipment manufacturers through long-term contractual relationships.

Steel operations

World-class mining business

With our global portfolio of 14 operating units with mines in operation and development, we are one of the largest iron ore producers in the world. Our main mining products are iron ore lump, fines, concentrate, pellets, sinter feed, coking coal, pulverised coal injection (PCI) and thermal coal. In the year ended December 31, 2015, ArcelorMittal mines and strategic contracts produced 73.7 million tonnes of iron ore and 6.29 million tonnes of coking coal and PCI.

Our iron ore reserves are estimated at 4.3 billion tonnes and total coking coal reserves are estimated at 265 million tonnes or 133 million wet recoverable tonnes. These long-life reserves provide a measure of security of supply and an important natural hedge against raw material volatility and global supply constraints.

R&D provides the technical foundation for our sustainability and commercial success, and we believe our R&D capabilities lead the industry. In 2015, we invested $227 million in R&D, and opened a new facility in Brazil. We maintain strong academic partnerships with universities and other scientific bodies, and work closely with customers to develop new steel products and solutions. We employ over 1,300 people in our global R&D centres.

In R&D, we focus on three main areas:

Maintaining the competitiveness of steel – especially in automotive

Automotive contributed 19% of sales in 2015. We have been pioneering Advanced High Strength Steels (AHSS) grades and manufacturing processes that help customers create lighter yet stronger vehicles, and meet demanding new targets for fuel economy. With each new product, we develop the accompanying technology our customers need to use it efficiently, and give them a detailed lifecycle analysis of the environmental footprint of the product from manufacture through use to final disposal and recycling, including CO2. This work was shortlisted for a World Steel Association Award in the Excellence in Life Cycle Assessment category in both 2014 and 2015.

Creating niche products to grow non-auto segments

Construction contributed 18% of direct sales in 2015. Our R&D strategy is to deliver similar breakthrough advances to those we have achieved in automotive since 2010. In 2015 we made an important breakthrough for line-pipe and offshore markets, testing a new cooling technology at our Burns Harbor plant in USA. We will launch phase two in 2016, and introduce it at our European sites in the coming years.

Improving our steelmaking processes

Creating unique processes helps us sustain our competitiveness, and, in 2015, we deployed a record 202 innovative technical solutions. Our most significant was the industrialisation of a revolutionary coating technology in partnership with CRM Group in Liège, Belgium. We are investing €60 million in a new production line for this technology at the Kessales plant in Liège, through our subsidiary Arceo, S.A..
