A method for producing a substantially nonporous, austenitic stainless steel consisting essentially of, in weight percent, from 10 to 30% chromium, from 21 to 45% manganese, from 0.85 to 3% nitrogen, up to 1% carbon, up to 2% silicon, balance essentially iron and residuals; which comprises the steps of: preparing a melt containing from 10 to 30% chromium, from 15 to 45% manganese, up to 1% carbon up to 2% silicon and balance iron and residuals, alloying the melt at an ambient pressure of about one atmosphere, with nitrogen in an amount of from 0.85 to 3%; balancing the elements in accordance with the following equations: 30 (%C +%N) +0.5 (%Mn) ≥ 1.5 %Cr +1.5 (%Si) %Cr +0.8 (%Mn) -11.88 (%N -0.1) -28.25 ≥0 and solidifying the melt.
