SG Ductile Iron Casting

Ductile Iron also know as SG IRON (SPHERIODICAL GRAPHITE DUCTILE IRON) Ductile iron is created by an alloying process which converts the crack-promoting graphite flakes of gray iron into nodules. With this micro structural transformation, the metal acquires superior ductility, elongation characteristics, and machinability. The ductile iron family offers the design engineer a unique combination of strength, wear resistance, fatigue resistance, and toughness, as well as excellent ductility characteristics. In all its grades, ductile iron exhibits mechanical properties that make it an ideal alloy for investment casting.
