.... The characteristic properties of CG irons have been demonstrated over a rather wide range of carbon equivalent (CE) values, extending from hypoeutectic (CE = 3.7) to hypereutectic (CE = 4.7), with carbon contents of 3.1 to 4.0% and silicon in amounts of 1.7 to 3.0%. At constant silicon levels, a lower CE slightly...
