Abstract

A method for generating a flat steel product comprising the steps of: melting a steel melt, comprising, in addition to Fe and unavoidable impurities (in wt %) C: 0.5-1.3%, Mn: 18-26%, Al: 5.9-11.5%, Si: <1%, Cr: <8%, Ni: <3%, Mo: <2%, N: <0.1%, B: <0.1%, Cu: <5%, Nb: <1%, Ti: <1%, V: <1%, Ca: <0.05%, Zr: <0.1%, P: <0.04%, S: <0.04%; casting the steel melt into a cast strip; heating the cast strip to an initial hot-rolling temperature of 1100-1300° C. at a heating rate of at least 20 K/s; hot rolling the cast strip into a hot strip; cooling the hot strip within 10 seconds after the hot rolling at a cooling rate of at least 100 K/s to <400° C.; and winding the cooled hot strip into a coil at a coiling temperature of up to 400° C.
