3. Properties of flake graphite cast irons
The properties of cast irons are determined by their structure, which depends on a series of manufacturing factors. Chemical composition is just one of these manufacturing factors. As we have seen, other factors also influence the structure of cast iron, with consequences for its mechanical properties.
Grey cast iron is produced in blast furnaces, cupola furnaces or induction furnaces. These different melting processes use different charges to obtain cast iron of a given composition. Because of these differences, the liquid metal does not behave in the same way during solidification, and mechanical properties depend on the solidification mode (figure
