FIELD: metallurgy.
SUBSTANCE: invention refers to metallurgy, and namely to austenitic stainless steel development for chemical industry. Steel contains in wt %: C: max. 0.050, Si: 0.01-1.00, Mn: 1.75-2.50, P: max. 0.050, S: max. 0.0100, Ni: 20.00-24.00, Cr: 23.00-27.00, Mo: 1.80-3.20, N: 0.110-0.180; Fe and admixtures are the rest. Steel grain size No. Determined in according to JIS G0551 (2005) is at least 6.0, and part of area occupied by phase σ does not exceed 0.1%.
EFFECT: steel has high temperature strength and corrosion resistance in nitric acid.
