The ferrous Metals and alloys used : Pig Iron Cast Iron Wrough Iron Steels and Alloy Steels METROLOGY

PIG IRON Gray cast Iron Casting of Machine parts, Machined easily White cast Iron : Very Hard, Very difficult to machine (Chilled cast Iron) can not be weleded. Molleable cast Iron : Increased ductility, tensile strength and toughness, produced from cast Iron Nodular Cast Iron : Similar to malleable cast Iron, Produced without any heat treatment. Wrouht Iron : 99.9% of Iron production puddling process astron or byres process shaft. CAST IRON

STEEL (PLAIN CARBON STEEL) Classified according to their carbon content. Dead mild steel0.1 to % CarbonUses wire, road & Sheets Mild Steel0.15 to 0.3 % carbonGeneral workshop process Medium Carbon steel0.3 to 0.7 % carbonAxles, drop forgines, High tensile tubes, wires, agriculture tool.
