FIELD: machine building.
SUBSTANCE: the steel in question is of the following composition, weight%: carbon 0.4-0.6; silicon 0.4-0.6; manganese 1.0-1.5; titanium 0.1-0.2; vanadium 0.08-0.12; chromium 0.3-0.5; boron 0.002-0.006; nitrogen 0.02-0.04, strontium 0.005-0.015, molybdenum 0.15-0.25, nickel 0.8-1.2, calcium 0.004-0.008; iron - the rest. The innovation provides increased hardenability of steel.
EFFECT: increased hardenability.
