    摘要: A dual-phase steel, a flat product and processes for the production thereof. The dual-phase steel having a strength of at least 950 MPa, good deformability, and good surface finish. It is possible, when a simple production process is used, for the flat product produced from this steel to be formed into a complexly formed component, such as part of a car body, either uncoated or provided with an anti-corrosion coating. The steel according to the invention has a structure comprising 20-70% martensite, up to 8% retained austenite and the remainder ferrite and/or bainite and has the following composition (in % by weight): C: 0.050-0.105%, Si: 0.20-0.60%, Mn: 2.10-2.80%, Cr: 0.20-0.80%, Ti: 0.02-0.10%, B:

    摘要: A hot-rolled flat steel product having a tensile strength of at least 1100 MPa, good elongation properties, and good deformation properties. The flat steel product is produced from a complex phase steel, which contains, in addition to iron and inevitable impurities (in % by weight), C: 0.13-0.2%, Mn: 1.8-2.5%, Si: 0.70-1.3%, Al: 0.01 to 0.1%, P: up to 0.1%, S: up to 0.01%, Cr: 0.25-0.70%, optionally Mo, the total of the Cr and Mo contents being 0.25-0.7%, Ti: 0.08-0.2%, B: 0.0005-0.005%, and a structure which consists of at the most 10% by volume of residual austenite, 10-60% by volume of martensite, at the most 30% by volume of ferrite and at least 10% by volume of bainite. Also, a method for producing such a flat steel product.

    摘要: The invention relates to a wheel rim for a motor vehicle which can be economically manufactured, with a wheel disc made of steel sheet and a rim flap running around the circumference of the wheel disc. Due to the fact that the steel sheet of the wheel disc is formed from at least three superimposed steel layers, joined to one another by roll-bonding in a non-detachable manner, of which the inner core layer has a lower strength than the outer layers, it is thereby guaranteed that the wheel rim according to the invention, with a low weight, can safely accommodate the forces arising in practical operation.
