... largely by effects on the amount and shape of graphitic carbon present in the casting. For example, in low-alloy cast irons, depth of chill or the tendency of the iron to be white as-cast depends greatly on the carbon equivalent, the silicon in the composition, and the state of inoculation. The addition...
