Product Material and Uses


1. Normally produce with gray iron HT200, HT250, ductile iron 65-45-12, 60-40-18, 80-55-06, 80-60-03, etc.
2. The ductile iron casting products are widely used for Auto-cars, trains, trucks, vehicle components, mining machinery components, agricultural machinery parts, textile machinery parts, construction machinery parts, valves and pump parts, etc.

 

Applications

Much of the annual production of ductile iron is in the form of ductile iron pipe, used for water and sewer lines. It competes with polymeric materials such as PVC, HDPE, LDPE and polypropylene, which are all much lighter than steel or ductile iron; being softer and weaker, these require protection from physical damage.

Ductile iron is specifically useful in many automotive components, where strength must surpass that of aluminum but do not necessarily require steel. Other major industrial applications include off-highway diesel trucks, Class 8 trucks, agricultural tractors, and oil well pumps. In wind power industry nodular cast iron is used for hubs and structural parts like machine frames. Nodular cast iron is suitable for large and complex shapes and high (fatigue) loads.

What is the difference between Ductile Iron and Cast Iron?
Cast iron refers to all iron parts that are cast and have a high carbon content, but in normal usage, “cast iron” refers to gray iron, the cast parts with weaker iron structures containing graphite flakes. Ductile iron must specifically have the spherical graphite structure in the metal.
Regular cast iron can be cast cheaply, machined very easily, and strength can be added through heat treating. Gray iron lacks the strength and durability of ductile cast iron. Ductile iron castings are not much more expensive than gray iron castings yet if there is no need for the benefits of ductile iron you should probably stick with the gray iron castings.
      

 

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.
