Abstract
Ductile steel alloys contain about 2-30 per cent of chromium, up to 0,5 per cent of carbon, and more than about 4 times as much niobium as carbon. The preferable niobium content is between 8 times the carbon content and 8 times the carbon content plus 2 per cent. The alloys preferably contain not more than about 1 per cent of manganese, 1 per cent of silicon, and 1 per cent of impurities. Steel alloys each containing chromium and one of the metals uranium, molybdenum, and tungsten instead of niobium are referred to by way of comparison.
