Abstract: A method for producing a cast strip of molten metal, in which the molten metal passes through a casting gap defined by two oppositely rotating casting rollers and is shaped into the cast strip, as well as the cast strip that is produced. By providing the cast strip in the casting gap with a different thickness in a first length section extending in the longitudinal direction of the cast strip than in a second length section bordering thereon, a metal strip is produced that has length sections with different thicknesses.

Abstract: A method for producing a cast strip of molten metal, in which the molten metal passes through a casting gap defined by two oppositely rotating casting rollers and is shaped into the cast strip, as well as to a cast strip. The inventive method makes it possible to produce a metal strip that has length sections with different thicknesses. According to the invention, this is achieved in that the cast strip is in the casting gap provided with a different thickness in a length section extending in the longitudinal direction of the cast strip than in a second length section bordering thereon.

Abstract: A stainless steel and a flat cold product produced therefrom, which can be easily produced in an economical manner. A steel according to the invention, in the cold-rolled state, has a microstructure with 5-15% by volume ?-ferrite and austenite as the remainder. It contains (in % by weight): C: 0.05-0.14%, Si: 0.1-1.0%, Mn: 4.0-12.0%, Cr: >17.5-22.0%, Ni: 1.0-4.0%, Cu: 1.0-3.0%, N: 0.03-0.2%, P: max. 0.07%, S: max. 0.01%, Mo: max. 0.5%, optionally one or more elements from the group consisting of Ti, Nb, B, V, Al, Ca, As, Sn, Sb, Pb, Bi, and H wherein Ti: max. 0.02%, Nb: max. 0.1%, B: max. 0.004%, V: max. 0.1%, Al: 0.001-0.03%, Ca: 0.0005-0.003%, As: 0.003-0.015%, Sn: 0.003-0.01%, Pb: max. 0.01%, Bi: max. 0.01%, H: max. 0.0025%, and remainder Fe and unavoidable impurities.
