Increase the acceptance of trace elements in steels (SPÅRA2)
Purpose and goal
SPÅRA2 aims to scientifically map how trace elements such as copper and phosphorus affect the microstructure and product properties of steel, driven by the industry’s transition toward increased use of scrap-based metallurgy.
Expected effects and result
The results are expected to contribute to greater acceptance of trace elements, thereby enabling increased use of scrap and improved circularity. The project will strengthen the competitiveness of Swedish steel producers and users during the green transition. The project is time-critical, as the transition is already underway, with developments such as the new steel plant Stegra (2026) and a new scrap-based electric arc furnace at SSAB Oxelösund (2026).
Planned approach and implementation
The project includes systematic studies of low-alloy steels, electrical steel, high-speed steel, and stainless steel grades. Through joint testing conducted by research institutes and participating companies, new knowledge will be generated on the impact of trace elements on aspects such as microstructure, mechanical properties, formability, corrosion, and magnetic properties.
