Mar 01, 2001 · The impact toughness of SG-iron is influenced significantly by matrix microstructure. Energy of about 230 103J/m2 is required to fracture a ferritic matrix SG-iron. Pearlitic grades of SG-iron
Austempered Ductile Iron ::Total Materia ArticleCast iron contains more than 2% carbon, present as a distinct graphite phase. In ductile cast iron the graphite occurs as spheroids or spherulites rather than as individual flakes as in gray iron. Ductile iron exhibits a linear stress-strain relation, a considerable range of
Pig Iron comprises three main types:BASIC PIG IRON, used mainly in electric arc steelmaking, FOUNDRY PIG IRON used in mainly in the manufacture of grey iron castings in cupola furnaces, and NODULAR PIG IRON (SG GRADE) used in the manufacture of ductile iron castings.

PROPERTY ENHANCEMENT OF SPHEROIDAL GRAPHITE SG iron is an alloy of iron and carbon having nodules or spheroids of graphite embedded in a grades of ductile iron commonly have the structures which are ferritic, ferritic/pearlitic or pearlitic. Controlled processing of the molten iron precipitates graphite as spheroids rather than
SG Iron Castings - CR4 Discussion ThreadMay 05, 2007 · British Standard Specification for "Iron Castings with Spheroidal or Nodular Graphite -BS. 2789.1961.
