    Abstract

    The Swedish bearing steel industry dates back a century. Already in the early days, Swedish bearing steels were characterized by an exceptionally high quality due to the availability of pure iron ores that made it possible to produce bearing steels by the acid open-hearth processes. Development of the ladle furnace process using inductive stirring made it possible to use the much more flexible and cost effective electric arc melting process. The strive to produce ever better steel products has been strong, driven by increasing demands on final product performance. Developments in steel processing technology, process know-how, and understanding of the complex relationships governing steel cleanliness are worth noting. Methods used have undergone vast improvements in recent times and the development continues. The same situation is valid for the quality assurance methods employed in the manufacturing of steel products.
