Abstract

The invention relates to metallurgy, in particular to steels that can be used in power engineering and mechanical engineering for welded structures operating under pressure. The aim of the invention is to increase the mechanical properties in cross-sections of 500 to 700 mm of welded bodies of nuclear reactors with a capacity of 2 million kW while maintaining resistance to embrittlement under the influence of heat. The steel contains by weight. %: carbon 0.13 to 0.18 silicon 0.17 to 0.37 manganese 0.30 to 0.60 chromium 1.7 to 2.5 nickel 2.1 to 2.5 molybdenum °.5 to 0.7 vanadium 0.05 to 0.12 nitrogen 0.005 to 0.012 aluminum 0.01 to 0.035 copper 0.11 to 0.20 arsenic 0.003 to 0.008 phosphorus 0.003 to 0.012 antimony 0.001 to 0.005 lead 0.001 to 0.004 iron and other impurities, with the total content of antimony, lead and phosphorus corresponding to the relationship: Sn + 2Sb + 3P < 0.039.
