FIELD: steelmaking. SUBSTANCE: invention relates to austenite sulfurous stainless steel with improved workability characteristics, in particular, applied in the field of high-speed cut turning as well as in manufacture of parts from bar on particularized bar automates. Steel contains (in wt %): carbon, at most 0.1; silicon, at most 2; manganese, at most 2; nickel, 7-12; chromium, 15-25; sulfur, 0.10- 0.55; copper, 1-5; calcium, above 10-4; oxygen, above 10-4; iron, the balance. Calcium to oxygen ratio is 0.2-0.6. EFFECT: improved workability characteristics. 6 cl, 2 dwg, 2 tbl
