Nodular Acicular Cast Iron Rolls. The strength of the spheroidal graphite (SG) or nodular cast iron is a result of a change in morphoglgy of flake graphite into graphite spheroids. The lower surface area to volume of the spheroids increases its fracture toughness and hence reduces crack propagation. SG iron is an excellent conductor of heat and ...
