Low Alloy Steels & Stainless (CLASS) Seminar
Theme: Recycled Material and Impurity Elements – Effects on Structure, Properties and Processability.
The seminar gathered around 40 participants from the industry within the Low Alloy Steels & Stainless (CLASS) research consortium. The focus was on how recycled materials and impurity elements affect the properties of steel and future manufacturing capabilities.
The morning session featured insightful presentations on secondary raw materials, scrap quality, and circular opportunities for contaminated by-products. Speakers included Andreas Feldmann (KTH), Rutger Gyllenram (Kobolde & Partners), and Maciej Kaplan (Greeniron), who highlighted both challenges and solutions related to future material flows.
After a short break, the topic shifted to tramp elements and their impact on steelmaking. Hans Magnusson (Swerim) and Sonia Guehairia (KTH) presented technical strategies and analytical methods to manage trace elements and understand their influence on microstructure and material properties.
In the afternoon, the focus turned to industry trends. Erland Nylund (Swerim) offered a system perspective on scrap flows, and Jerome Senaneuch together with Henrik Sieurin (Scania) shared Scania’s path toward 100% green steel. Participants also engaged in an open discussion on future challenges, collaboration opportunities, and innovation potential.
The day concluded with joint reflections and an optional lab tour at Swerim.
