FIELD: metallurgy; ferrous.
SUBSTANCE: steel is used in the machine building industry. The steel has the following composition, % weight: carbon 0.17-0.23, silicon 0.1-0.17, manganese 0.1-0.2, chromium 0.1-0.2, nickel 0.4-0.8, vanadium 0.05-0.15, molybdenum 1.0-1.5, calcium 0.005-0.007, barium 0.005-0.007, copper 2.5-3.5, iron being the remaining. The steel machinability and the labour efficiency increase.
EFFECT: increased steel machinability and labour efficiency.
