ABSTRACT:
A cold strip for manufacturing deep-drawn, case-hardened precision components, particularly rolling bearing and engine components, in which a core material (2) is roll clad at least on one side with a cladding material (3), characterized in that the core material (2) is a low-carbon cold or hot steel strip and the cladding material (3) is a cold or hot strip with increased carbon content, the core (2) and the cladding material (3) having different physical and chemical properties which complement each other, particularly with regard to deep-drawability, hardenability, constant reverse-bend fatigue strength and wear resistance.
