ArcelorMittal S.A. is a very large company that makes steel. It is based in Luxembourg City, Luxembourg. This company is one of the biggest steel makers in the world. In 2024, it was the second largest, making 58 million metric tonnes of steel.

The company has steel factories in 15 different countries. These include 37 large and small steel-making places. In 2024, most of its steel was made in Europe (53%) and the Americas (38%). The rest (9%) came from other countries like South Africa and Ukraine.

ArcelorMittal also gets many of its own raw materials. This means they mine 58% of the iron ore they need. They also produce 90% of their own coke and 54% of their scrap metal. This helps them control their production.

The company is partly owned by Lakshmi Mittal and his family. They own about 39.88% of the company. The rest of the company's shares are traded on stock markets.

ArcelorMittal mines iron ore in several countries. These include Brazil, Canada, and South Africa. The company makes a lot of steel for cars. About 15% of all steel used in cars comes from ArcelorMittal. They make over 200 different types of steel for cars. One special type, Usibor 2000, was released in 2016. It is much stronger than other steels used for cars.
