Development Process of High-Silicon Steel Grade 54SiCr6 for Automobile Spring Steel Production With EAF Route, From Scrap Yard to Wire Rod Coil: Lessons Learned and Future Improvements

The paper describes the positive experience at ABS (Acciaierie Bertoli Safau) during the development of the whole manufacturing process (from meltshop to rolling mill) of high-silicon grade 54SiCr6 for automobile suspension springs. The evolution of this learning process is presented, with focus on the implemented aspects (i.e., materials, process parameters, equipment, production scheduling) that proved to be fundamental for the achievement of the product requirements (i.e., steel chemical composition, microinclusion morphology and quantity, blooms and wire rod internal and surface quality). The satisfactory feedback from product performances confirms the effectiveness of the development path and opens the door for future improvements.
