What are the Benefits of Ductile Iron?

 

Ductile iron castings are very strong compared to regular cast iron (gray iron). The tensile strength of cast iron is 20,000 – 60,000 psi while ductile iron starts at 60,000 psi and can go to 120,000 psi. The yield strength for ductile iron is generally 40,000 – 90,000 psi but the yield strength of cast iron is so low it is considered not measurable.

Let us put strength in a different way. We have seen gray iron parts break when they hit the ground after falling ten feet. With a ductile iron casting, you can hit the part all day long with an eight-pound sledge hammer and it is not likely to crack.

What causes the problem for gray iron is those graphite flakes which encourage fractures along the flakes, while the nodules in ductile iron work at keeping the iron together. Given the exact same scenario of the same part made from the two different metals, while the brittle gray iron wants to crack, the ductile iron wants to bend.

Ductile iron also has what is called excellent wear resistance because of the graphite in the iron. When you have something rubbing against ductile iron, the ductile iron wears away much slower than many other metals. The wear resistance is partly from the graphite structures that can act like a dry lubricant on the iron.

Ductile iron also dissipates (gets rid of) heat very well and can be machined fairly easily, though ductile iron is harder to work with than regular gray cast iron. Ductile cast iron dampens vibration and sound much better than steel would making ductile iron a good match for use on large machines.

 

Recent development of ductile cast iron production technology in China

 

With the constant growth of national economy, the castings output in China increases quickly. China has been ranked the top manufacturer of casting production in the world since 2000. The casting output had reached 24,420,000 tons in 2005, accounting for about 28.5% of the world's total output [1]. In addition, the output of ductile iron had also developed rapidly, which reached 5,838,000 tons in 2005, increasing to 2.46 times of output in 2000. The ratio of ductile iron castings to total castings increased from 18% in 2000 to 23.9% in 2005. Over the past five years, the production of centrifugal-cast iron pipe had achieved an average 40% growth in China, to 1.9 million tons in 2004.

Moreover, huge quantities of various centrifugal-cast iron pipes have been exported to Southeast Asian countries. However, the ratio of ductile iron castings to total castings in developed countries, such as France (40.8%), the United States (32.88%) and Japan (28.9%), is still beyond that of China in 2005. With the development of automotive and cast pipe industries, as well as the gradual improvement of ductile iron casting quality in China, the applications of ductile iron castings will be continuously expanded. In the "11th Five-Year Plan," the production of ductile iron in China will be greater than that of the world's average level, and will continue to be an important casting alloy for various engineering fields in the future. Therefore, further stabilizing ductile iron production process, improving ductile iron quality, exploiting and introducing new technologies for ductile iron production, are still an important task for Chinese casting manufacturing industry.
