TRIP steels - ArcelorMittal
TRIP steels offer an outstanding combination of strength and ductility as a result of their microstructure. They are thus suitable for structural and reinforcement parts in complex shapes. The microstructure of these steels consists of islands of hard residual austenite and carbide-free bainite dispersed in a ductile ferritic matrix.
