Sweden is leading a revolution in steel production around the world: from a carbon-intensive industry to the main producer of fossil-free steel. The country’s steel industry is based on a dual strategy, producing high-quality special steels for demanding applications such as bearings, tools and springs and at the same time developing hydrogen-based reduction technologies. Already, major players such as SSAB are delivering SSAB Zero™ (from recycled steel with fossil-free energy) and SSAB Fossil-Free™ (using HYBRIT technology with green hydrogen) to customers ranging from automotive giants to defense manufacturers and energy companies. Combined with Sweden’s access to renewable electricity and high-grade iron ore, this technology shift makes the Swedish steel industry a crucial supplier for the green transition in Europe.
The market is worth an estimated €12.6 billion, with main players including multinational groups such as Voestalpine (owner of the historic Uddeholm brand) and domestic champions such as SSAB and Ovako. Here are the five strongest players in this high‑value manufacturing space, from fossil‑free flat steel producers to specialists in engineering steel and tool steel.

FAQ
What is the difference between SSAB Zero and SSAB fossil‑free steel?
SSAB Zero™ is made from recycled steel scrap processed using fossil‑free energy sources (such as biogas and renewable electricity). It is aimed at circular applications. SSAB Fossil‑free™ steel is made from virgin iron ore using the HYBRIT process, where green hydrogen replaces coal for reduction. It is targeted at applications where high strength and virgin material properties are required and it emits water instead of CO₂. .
Does Ovako make stainless steel?
Ovako used to be focused on engineering carbon steels, but now, with the addition of Hybrid Steel®, it offers corrosion resistance comparable to stainless steel but with the strength and weldability of engineering steel. For complete stainless steel mold applications, manufacturers usually use products from Uddeholm or other suppliers.
What is Uddeholm famous for?
Uddeholm is the world’s leading producer of tool steel and mold steel. It is the gold standard for plastic injection molds (e.g., Uddeholm Ramax HH) and die-casting tools. The company has been in Sweden for more than 350 years and is known for providing materials that ensure high polishability and long service life for tools.
Is Stegra already producing steel?
Stegra is still under construction as of mid-2026. The company hopes to begin commercial production in 2026. They have the land, the funding and partnerships (with LKAB for iron ore pellets, for example) but are not a mass producer yet.
What are the main products of Sweden’s steel industry?
Sweden is a specialist in high-value-added steel. The key outputs are flat products (sheets/coils from SSAB), long products (bars/rods/tubes from Ovako), tool steel (blocks/sheets from Uddeholm) and fasteners (screws/bolts from Bulten). The industry also produces large quantities of scrap-fed steel for buildings.
Why is Swedish steel considered “green”?
Swedish steel is “green” because the country has access to fossil‑free electricity (hydro and wind). Manufacturers like Ovako and SSAB have invested heavily in replacing fossil fuels (coal, natural gas, propane) with hydrogen or biogas in their production lines. Furthermore, high recycling rates and the unique HYBRIT technology (water instead of CO₂) contribute to producing steel with a fraction of the carbon footprint of the global average.
