Abstract
Disclosed is a multilayered steel composite which compatibly achieves properties such as strength and ductility that are incompatible in conventional steels and is excellent in strength, ductility, weldability, toughness and fatigue strength. Also, disclosed is a method for producing the multilayered steel which is produced by rolling with least two kinds of steels having different chemical compositions and microstructure or different mechanical properties, in combination.
