Cast ductile iron normally contains over 3 percent carbon; it can be bent, twisted or deformed without fracturing. Its mechanical properties are similar to steel, and far exceed those of standard cast irons.Ductile iron castings are solid metal objects that result from molten ductile iron being poured into voids in a mold. The ductile iron subsequently cools and solidifies in the shape of the void it occupies.What is in Ductile Iron? (Composition)If you were to do a chemical analysis of ductile iron, this is what you would normally find:Iron ~94%Carbon 3.2 – 3.60%Silicon 2.2 – 2.8%Manganese 0.1 – 0.2%Magnesium 0.03 – 0.04%Phosphorus 0.005 – 0.04%Sulfur 0.005 – 0.02%Copper <= 0.40%To improve the strength of ductile iron, additional tin or copper can be added. To improve corrosion resistance, copper, nickel, or chromium can replace anywhere from 15-30% of the iron.Common Ductile Iron GradesWhile there are many different ductile iron specifications, foundries routinely offer 3 common grades;Physical and Mechanical PropertiesASTM A536,Grade 60-40-18ASTM A536,Grade 65-45-12ASTM A536,Grade 80-55-06Tensile Strength, min, psi60,00065,00080,000Tensile Strength, min, MPa414448552Yield Strength, min, psi40,00045,00055,000Yield Strength, min, MPa276310379Elongation in 2 in. or 50 mm, min %18126Density lb/in30.2560.2560.256Density g/cm37.17.17.1Melting Temperature (Degrees F)2,100 – 2,1902,100 – 2,1902,100 – 2,190Melting Temperature (Degrees C)1,150 - 1,2001,150 - 1,2001,150 - 1,200Compressive Strength Ksi429429429Compressive Strength MPa296029602960UNSF32800F33100F33800
