Full-scale project on one-alloy steel for increased sustainability (OASIS2)
Purpose and goal
The OASIS project proposes a shift in alloy design for automotive industry by developing a single one-alloy steel capable of fulfilling the diverse properties currently met by 30- 40 different alloys in a typically automotive body. This one-alloy concept is designed to enhance circularity, reduce environmental impact, and streamline production across the automotive value chain.
Expected effects and result
The project continues the prestudy that demonstrated the feasibility of achieving ferritic, dual-phase, and martensitic microstructures from a single one-alloy steel concept through tailored heat treatments. Key deliverables include full-scale alloy production, cold and hot forming studies on demonstrator components, weldability and coatability trials. The project will also assess the effects of implementing a one-alloy grade along the value chain in a closed loop circular material flow.
Planned approach and implementation
Design and production full scale of 200 tonnes one-alloy concept. Hot-rolled and coldrolled, and also hot-dip galvanized. Concept is then evaluated for cold-forming, hotforming, corrosion, and weldability, following industrial practices. The design perspective is evaluated using a one-alloy concept, with possible future implementation effects.
