LOW-ACTIVATED HEAT-RESISTANT STEEL Russian patent published in 1995 - IPC

Abstract RU 2033461 C1

FIELD: ferrous metallurgy. SUBSTANCE: steel has additionally boron, titanium and cerium at the following ratio of components, wt.-%: carbon 0.1-0.2; silicon 0.02-1.0; manganese 0.5-2.0; chrome 10.0-13.9; tungsten 0.8-2.9; vanadium 0.05-0.45; titanium 0.01-0.10; boron 0.0005-0.0080; cerium 0.001-0100, and iron - the rest. Structural equivalent A must be A ≅ 11. Steel shows increased short-term mechanical properties and prolonged endurance limit, retained drop level of induced activity after neutron irradiation. EFFECT: enhanced quality of steel. 2 tbl
