CAST IRON

Cast Iron There are four basic types of cast iron - white iron, gray iron, ductile iron and malleable iron There are four basic types of cast iron white iron gray iron ductile iron malleable iron White Cast Iron Characterized by the prevalence of carbides, impacting high compressive strength hardness good resistance to wear Gray Cast Iron Characterized with graphite in the microstructure, giving good machinability good resistance to wear and galling Ductile Cast Iron Gray iron with small amounts of magnesium and cesium which nodulates the graphite, resulting high strength high ductility Malleable Cast Iron White cast iron heat-treated to improve higher ductility
