Results of a study of austenitic corrosion-resistant steels of the Fe – Cr – Ni–N–Si alloying system are studied. The steels possess higher parameters of strength (by 25 – 30%) and corrosion resistance (by a factor of 5 – 28) as compared to chromium-nickel steels of type 18–11 serving today in strongly oxidizing media. Comparative analysis of the properties of the new steels and of steel 03Kh18N11 (GOST 5632) widely used in the chemical industry is performed.
