FIELD: metallurgy.
SUBSTANCE: invention refers to composition of heat resistant steel for thermo power units with working temperature of steam to 650°C. Steel contains carbon, silicon, manganese, chromium, cobalt, molybdenum, tungsten, vanadium, niobium, calcium, cerium, nitrogen, boron, phosphorus, aluminium, tin, lead, arsenic, and iron at a following ratio of elements, wt %: carbon 0.11-0.14; silicon 0.15-0.20; manganese 0.40-0.60; chromium 10.0-11.0; cobalt 3.0-4.0; molybdenum 0.9-1.1; tungsten 0.9-1.1; vanadium 0.15- 0.30; niobium 0.04-0.09; calcium more, than 0.005-0.05; cerium more, than 0.02-0.05; nitrogen 0.03-0.07; boron 0.001-0.006; phosphorus not more 0.015; sulphur not more, than 0.010; aluminium not more, than 0.015, tin not more, than 0.006, lead not more, than 0.006, arsenic not more, than 0.006, iron - the rest.
EFFECT: upgraded thermo resistance, long-term strength and stress rupture ductility.
