SG Iron Casting | High-Strength Ductile Iron Castings | Indi

SG Casting refers to the casting of cast iron with spheroidal graphite microstructure. Unlike the traditional grey iron, where graphite is in flake form, SG iron contains graphite in nodular or spherical form. This special microstructure is developed by introducing minute quantities of magnesium or cerium into molten iron while casting. The resulting material is one that possesses steel’s strength and toughness but iron’s casting property and economy.
