Cast iron Wikipedia
Cast iron is a group of ironcarbon alloys with a carbon content greater than 2% Its usefulness derives from its relatively low melting temperature The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as thebertin and Sinatora [9] tested cast iron balls produced from Fe(12 to 25)Cr(16 to 35)C with carbide fractions of 13 to 40% by wet, ball milling with hematite (400600 HV), phosphate rock (about 300 HV) or quartz sand (about 1000 HV) as abrasives and noted that the effect of carbide volume fraction on the wear resistance of high chromium castMICROSTRUCTURE AND EROSIONCORROSION BEHAVIOUR
