Abstract
Thin-walled castings are made of a cast iron containing 2,5-4,3 per cent of carbon but substantially no free carbon and are then decarburized by heating in an atmosphere of moist hydrogen at a temperature of 1600-2000 DEG F. The iron may contain a small percentage, e.g. 0,35-0,55, of vanadium sufficient to prevent the formation of primary graphite in the casting. In an example, the cast iron contains 3,5 per cent of carbon, 1,0 of manganese, 1,0 of silicon and 0,35-0,55 of vanadium. The moist hydrogen may be produced by passing hydrogen through hot water at a temperature of 150-212 DEG F. and steam may be added to the gas so produced.
