The inventive method permits a cost-effective production of a steel strip (W) or sheet, which consists predominantly of Mn-austenite and which has increased resistance in comparison to the strips or sheets in prior art. To this end, a steel is melted, said steel containing at least the following alloy components (in wt. %): 15.00 24.00 % Cr, 5.00 12.00 % Mn, 0.10 0.60 % N, 0.01 0.2 % C, max. 3.00 % Al and/or Si, max. 0.07 % P, max. 0.05 % S, max. 0.5 % Nb, max. 0.5 % V, max. 3.0 % Ni, max. 5.0 % Mo, max. 2.0 % Cu, the remainder being made up of iron and unavoidable impurities. Said steel is cast in a casting gap formed between two rotating rollers (2,3) or cylinders into a thin strip (D) with a maximum thickness of 10 mm. The rollers or cylinders (2,3) are cooled to such an extent that the thin strip (D) in the casting gap (4) cools at a speed of at least 200 K/s.
