Abstract

A steel contains, in percent by weight: Carbon from 0.13 to 0.18 Silicon from 0.17 to 0.37 Manganese from 0.30 to 0.60 Chromium from 1.7 to 2.4 Nickel from 1.0 to 1.5 Molybdenum from 0.5 to 0.7 Vanadium from 0.05 to 0.12 Aluminium from 0.01 to 0.035 Nitrogen from 0.05 to 0.012 Copper from 0.11 to 0.20 Arsenic from 0.0035 to 0.0055 Iron and impurities-- the balance. This steel is preferable for use in the manufacture of nuclear reactors.
