Aperam

Aperam S.A. is a Luxembourg-headquartered metals group focused on stainless steel, electrical steel, specialty steels, alloys and recycling. It was established at the beginning of 2011 through the separation of ArcelorMittal’s stainless and specialty-steels activities and became an independently listed company. Its portfolio is aimed at applications where corrosion resistance, magnetic performance, strength, heat resistance, surface quality or other engineered characteristics are more important than the basic cost of carbon steel. The company serves customers in automotive, appliances, construction, energy, electrical equipment, transportation, food processing and general industrial markets. Its products are supplied in forms including flat products, strip and other processed steel and alloy materials, with specifications tailored to downstream manufacturing requirements. Stainless steel remains the central business, while electrical steel and specialty alloys extend the group into higher-value applications requiring controlled magnetic or mechanical properties. Aperam has an international operating and commercial footprint spanning more than 40 countries. Its industrial base includes facilities in Brazil, Belgium and France, alongside specialty-material operations and commercial activities in markets including China, India and the United States. The Brazilian business is historically associated with Acesita and Aperam South America. Aperam’s Brazilian production model has used charcoal derived from eucalyptus forests managed by the group rather than conventional coking coal. Its European facilities use electric-arc furnaces supplied in part with recycled scrap. These practices form part of the company’s effort to reduce the carbon intensity of its production compared with more coal-dependent steelmaking routes. The group’s corporate history reaches back beyond the Aperam name. The Brazilian operation was privatized in 1992 and acquired by Usinor in 1998. Usinor later joined Arbed and Aceralia to form Arcelor in 2001, and the business became part of ArcelorMittal after that group’s acquisition of Arcelor in 2006–2007. Aperam was subsequently separated as a dedicated stainless and specialty-steels company. The group has continued to expand its portfolio through acquisitions, including the purchase of Universal Stainless, completed in January 2025. A reference also identifies the completion of the Magnatec Group acquisition in April 2026; that development should be checked against current company and regulatory disclosures. Aperam is listed on Euronext Amsterdam and also has listings on the Brussels, Paris, Madrid and Luxembourg stock exchanges. Its competitive positioning is based on specialized materials, international production, recycling, technical expertise and the ability to serve demanding industrial customers rather than on commodity carbon-steel volume alone. Ownership and operating details can change, so current financial performance, capacity, shareholding and executive information should be verified through the company’s latest annual report and investor-relations disclosures.

Aperam was created at the start of 2011 when ArcelorMittal separated its stainless-steel and specialty-steels activities into a distinct company. The separation reflected the different economics and customer requirements of stainless and engineered steels compared with mainstream carbon-steel production. Aperam began operating as an independent listed group with a portfolio centered on stainless steel, electrical steel, specialty steels and alloys. The company’s industrial history predates the Aperam brand. Its Brazilian operations are largely descended from Acesita, a Brazilian stainless-steel producer that was privatized by the Brazilian government in 1992. Usinor acquired the business in 1998. In 2001, Usinor combined with Arbed and Aceralia to create Arcelor. Following Arcelor’s takeover by Mittal Steel and the subsequent formation of ArcelorMittal, the Brazilian and European stainless activities became part of the enlarged group. They were later transferred into Aperam when the new company was spun out. Aperam’s production footprint has included important facilities in Brazil, Belgium and France, with additional specialty-material operations and commercial activity in China, India, the United States and other markets. The group serves customers in more than 40 countries. Its product strategy combines large stainless-steel activities with more specialized electrical steels, specialty steels and alloys. This gives Aperam exposure to sectors such as automotive, appliances, construction, energy, electrical equipment and general industry, where material performance and consistency can be decisive factors. The group has highlighted differences in its production routes across regions. In Brazil, eucalyptus forests owned and managed by the group provide charcoal used in the production process, replacing the coking-coal route used in conventional integrated steelmaking and reducing the facility’s carbon footprint. European facilities use electric-arc furnaces supplied with scrap, linking production to a recycling-based feedstock model. Recycling is also part of the broader business proposition, reflecting the recoverability and circularity of steel. Aperam has remained an international, publicly traded company rather than a subsidiary of ArcelorMittal. It is listed on Euronext Amsterdam and has listings on the Brussels, Paris, Madrid and Luxembourg exchanges. The Lakshmi Mittal family held a significant minority stake according to a June 2021 ownership reference, although current ownership should be checked in the latest filings. The company has continued to reshape and extend its portfolio through acquisitions, including Universal Stainless in January 2025 and a reference-reported Magnatec Group transaction in April 2026. These developments are intended to strengthen Aperam’s position in specialty and higher-value stainless materials, but their current operational and financial effects require confirmation from up-to-date disclosures.

A global supplier of higher-value stainless, electrical and specialty metal materials for demanding industrial and engineering applications, with an emphasis on technical performance, recycling and lower-carbon production routes.

• Stainless SteelStainless-steel materials

  Aperam’s principal product family serves automotive, appliances, construction, energy, food processing and industrial customers. Stainless products are selected for corrosion resistance, surface quality, durability, formability and ease of fabrication. The portfolio includes flat products and strip in grades and finishes adapted to downstream manufacturing requirements.

• Electrical SteelElectrical and magnetic steels

  Electrical steel is designed for applications in which controlled magnetic behavior is important. Aperam supplies this category for electrical equipment and industrial uses where magnetic losses, efficiency and dimensional consistency affect the performance of motors, transformers or related systems. Exact grades and product forms vary by application.

• Specialty SteelsEngineered steels

  Specialty steels address applications that require a more controlled combination of strength, toughness, corrosion resistance, wear resistance or process performance than standard grades. The category supports Aperam’s move toward technically differentiated materials and complements its mainstream stainless-steel operations.

• Specialty AlloysSpecialty alloys

  Aperam’s specialty-alloy activities target demanding environments in which heat resistance, corrosion resistance, wear resistance or other engineered properties are critical. These materials are used in selected industrial and high-performance applications, with product specifications determined by the customer’s operating conditions.

• Recycling and Recycled-Metal SolutionsMetal recycling

  Recycling is part of Aperam’s industrial model and sustainability positioning. Electric-arc production in Europe uses scrap as a major feedstock, allowing recovered steel to re-enter the production cycle. The activity supports customers seeking durable materials with a more circular supply-chain profile.
