General properties of cast iron. Cast iron is highly favoured for its ability to be easily cast into complex Under this system, grey cast irons are graded according to their tensile strength, with class 20 A popular grade of white iron is high chrome white irons, ASTM A532. This contains nickel and...
Mar 25, 2016 · CAST IRON SKILLET 4. ASTM-888 CAST IRON PIP 5. COMPOSITION All cast irons contain more than 2% C. Cast iron is the alloy of carbon with 1.7 to 4.5% carbon and 0.5 to 3% silicon. But in some alloy it has Manganese 0.5 to 1.0%, Phosphorous 0.1 to 0.9 %, & Sulphur 0.07 to 0.10%. 6.
SG Iron is a type of cast iron that has been treated while molten with an element such as magnesium or cerium to induce the formation of free graphite as nodules or spherulites. The followings are the grade requirement to the chemical components and physical properties, and also grade comparison chart.

Dura-Bar® G2 is a pearlitic gray iron containing Type A graphite. G2 is built around ASTM A48 Class 40 gray iron, which is validated from a separately cast bar. These continuous cast bars made to this robust specification are a good fit for a variety of applications due to its good machinability, wear resistance and vibration damping properties.
The presence of Sb in one of the cast alloys controlled the growth of graphite nodules in these heavy section ductile iron castings; however low impact toughness was recorded. The matrix structure of ductile cast iron showed a significant influence not only on the strength and impact properties but also on the fracture mode during testing.
Ductile cast iron, or spheroidal graphite cast iron, is much more mechanically resistant than grey cast iron. This type of cast iron is obtained by the addition of magnesium. According to the grade used, ductile cast iron can be impact resistant at low temperatures, and resistant to creep and oxidation at high temperatures.
Dura-Bar® ductile iron is often used as an alternative to plain carbon steel and has similar strengths with excellent free machining properties. Dura-Bar® 65-45-12 is a good replacement for low-carbon steel grades such as 1018, 1117, 1212 and 12L14. 80-55-06 can be an alternative to the medium-carbon steels such as 1141, 1144 and 1045.
