<jats:title>Abstract</jats:title><jats:p>Interstitial atoms are most effective in strengthening austenitic steels. In stainless grades, chromium strongly reduces the solubility limit of carbon. High‐nitrogen contents require costly pressure or powder metallurgy to dissolve N in the melt. The combination of both elements comes with a high‐interstitial solubility at normal pressure of air. Sand casting with 18 mass% Cr and Mn each and 0.85 mass% (C + N) were industrially produced. The investigation revealed: proof strength <jats:italic>R</jats:italic><jats:sub>p0.2</jats:sub> = 457 [MPa], true fracture strength <jats:italic>R</jats:italic> = 1714 [MPa], fracture elongation <jats:italic>A</jats:italic> = 44%, notch impact toughness KV = 290 J combined with a DBTT of −94°C, an impact wear resistance comparable to Hadfield steel X120Mn12 but combined with a good corrosion resistance. Deep freezing and cold working does not effect the low relative magnetic permeability. This unique combination of properties offers advantages in application.</jats:p>
