The Difference Between Ductile Iron Casting and Gray Iron Casting

Cast Iron Shrinkage Defects

Cast iron shrinkage defect has a great influence on the quality of cast iron. It will reduce the tensile strength and elongation, thus causing the iron casting to crack or penetrate in the shrinking area.

Today, based on my work experience at Yide Casting, I will introduce you to three types of shrinkage.

1. Sink on the surface

On the rough casting surface, you can see sinking pits. These pits are caused by shrinkage below the surface. Just like the photo below. This shrinkage will affect the size of the area and affect its physical properties. Generally, this shrinkage is unacceptable.

2. Large shrinkage holes inside of cast iron

You will not see this shrinkage on the surface. But after processing, this will be very obvious. You will see many large and small pores in the constricted area. Of course, this shrinkage is also unacceptable and very harmful to the application.

3. Small shrinkage holes inside of cast iron

Sometimes, after processing, you will see very small pores. Sometimes they cannot even be seen with the naked eye, but they can be inspected with a magnifying glass. Or, sometimes, you can refine them through water pressure or oil pressure testing. These shrinkages will cause the low density of cast irons, making them unable to withstand high pressures.


Obviously, shrinkage is very harmful to iron castings. The main reason for the shrinkage is the unreasonable casting process, especially the gate size. After the shrinkage is found, the iron casting plant should adjust its gate system.

However, since most shrinkage defects are under the cast iron surface, how should we check?

1. Generally, you can allow the supplier to perform roughing, so that they can find shrinkage after processing. This method is the most obvious and economical method, because most iron foundries in China have in-house rough machining capabilities.

2. For the pump body or valve body, you can conduct a water pressure test or ask your supplier to conduct a random test on them. Although this method cannot guarantee that all castings are qualified, at least some problems will be found.

3. You can cut off the sensitive position to check the shrinkage rate. According to our experience, shrinkage usually occurs in the gate area and certain corner areas. Therefore, after finding the shrinking position, you can focus on checking these positions in the batch inspection. You can just cut off these locations with a saw, or you can ask the supplier to cut off these locations that may cause shrinkage according to your instructions.

Advantages and Disadvantages of Stainless Steel Casting Process

Advantages and disadvantages of stainless steel casting process


Everyone in the casting industry knows a fact. That is the mechanical properties of stainless steel casting are higher than that of cast iron, but its casting performance is worse than that of cast iron. Stainless steel casting belongs to investment or precision casting, with relatively high melting point. The molten steel is easily oxidized, due to poor fluidity and large shrinkage rate. From a practical perspective, stainless steel casting is suitable for casting of various types and alloys.


Advantages and disadvantages of the stainless steel casting process are as below:


First, due to the poor liquidity of the molten steel, the wall thickness of the steel castings should not be less than 8 mm, in order to prevent the cold shut and misrun. The structure of the pouring system strives to be simple, and the sectional dimension is larger than that of cast iron. Adopt dry casting or hot casting, and the casting temperature should be appropriately increased to 1520-1600 ℃. The fluidity can be improved since the casting temperature is high with large superheat, thus the liquid stays for a long time.


However, if the pouring temperature is too high, it will cause defects such as coarse grains, hot cracks, pores and sand burning. Therefore, the casting temperature of small, thin-walled and complex casting should be at the melting point +150 ℃; and of large, thick-walled casting +100 ℃.


We must take these measures to prevent the occurrence of shrinkage holes and cracks in stainless steel castings. 1. Making the wall thickness uniform, and avoid sharp and right angle structures, 2. Adding sawdust to sand mold, and coke to sand core. 3. Adopting hollow sand core and oil sand core to change the deformability and permeability of the sand mold and core.

The Smelting Process of Copper Alloy

The Density of Ductile Iron

The density of ductile cast iron is approximately 7.3 g/cm3, or 7.3 kg/liter, or 119.6 g/cm3. However, due to the material grade and shrinkage level, the density has a certain range of variation.

In other words, if the quality of pig iron used by the iron foundry is better and the shrinkage rate is smaller, then the density of ductile iron will be higher. Otherwise, the density of ductile iron will be lower. Therefore, it ranges from 7.1 to 7.3 g/cm3.

Iron foundries usually estimate the weight of rough castings by calculating the volume of ductile iron, so the density will be used. However, you cannot judge the quality of castings by density alone.

There are more factors that will affect it, such as spheroidization rate and cooling rate. Hence, it will be reasonable within this range.

2025 Made in China and ONE BELT, ONE ROAD Policy Impact on Iron Foundry

With the implementation of “Made in China 2025” and “One Belt One Road” construction, the rapid development of all walks of life will be promoted. At the same time, the scale of China’s metal casting enterprises is also increasing year by year.


With the rapid development of various application fields, industry concentration has gradually increased, and product quality has continued to improve. This shows that the foundry industry has entered a medium-to-high-speed development stage.


The China (Beijing) International Foundry Exhibition will continue to be held at the China International Exhibition Center (new hall). In this way, it promotes the innovation and development of the foundry industry and promotes in-depth cooperation and exchanges between enterprises.


As a foundry with a history of more than 20 years, Yide Casting will take this opportunity to meet the needs of different customers in countries along the “Belt and Road” with high quality, high technology and high quality. Use better cast iron products to show the world the capabilities of China’s manufacturing.

What Is Iron Casting?

What Is Iron Casting?

What Is Iron Casting?

Gray iron is the most common type of iron casting. Its properties are good, making it the preferred material for a wide variety of applications. Its properties include high hardness, tensile strength, compressive strength, fatigue strength, and resistance to corrosion. While this type of iron casting is highly versatile, its disadvantages include low tensile strength and low elongation. It is a great choice for applications that require high tensile strength.

Yide Casting produces medium and heavy castings with sectional sizes up to four inches. It is the only iron foundry to cast the full range of test bar sizes. Inoculated irons are stronger than base iron bars and have a greater scatter of tensile strength values. A six-inch-diameter section at this foundry shows tensile strength values below the SAE line. The tensile strength data on this material are based on the center portion of the 6-in.-pediatric sections.

Gray iron is highly resistant to cracks. Its mechanical properties are related to the percentage of graphite, and the carbon-equivalent value. The cooling rate and eutectic solidification interval play an important role in the tensile strength of gray iron. The section size affects the tensile strength. The ASTM Specification A 48 requires the selection of the test bar. If the gray metal has an elongation value of less than 0.5, it will be stronger. The failure section should be as large as possible.

When choosing an iron casting foundry, it’s important to choose one that processes ductile iron separately from gray iron. The former is more malleable and durable than ductile. However, some foundries process gray and ductile iron from the same charge material. For example, if a foundry was to process internal recycled scrap gray iron, the sulfur would remain in the material. The solution would be to use a reducing agent, such as CaO, to remove the sulfur.

Graphite is another element used in iron casting. Its gray color is a result of a process known as investment casting. The investment-casting process produces pieces with thin walls and is usually used for ductile iron. Centrifugal casting, on the other hand, has the advantage of reducing porosity and sturdiness of the finished part. In addition, the material is also more resistant to corrosion, which is a positive feature for the investment-grade material.

The gray iron found in commercial castings is the most affordable of the two types of iron. This type of iron has a high modulus of elasticity and is suitable for structural components that must be stiff. On the other hand, it is prone to thermal fatigue, so it is not recommended for housing and machinery bases. Its high tensile strength and elasticity to make it the best choice for these applications. It is a great choice for those who want to save money.

Casting Defects – Sand Mold, Metal Casting

Today, I will introduce you to various metal casting defects and pictures found in the manufacturing process of yide casting. These are common sand casting defects on the surface and inside of cast iron and cast steel parts.

1. Blowhole and Pinhole

This is a void defect, which is also divided into pinholes and underground pores. Pinholes are very small holes, some can be seen on the surface. Underground air holes can only be seen after machining or grinding.

After machining or grinding, most underground pores can be found. If the surface is flat, our yide casting can inspect them by ultrasonic flaw detector.

3. Sand Inclusion and Slag Inclusion

These defects are also called scab or black scab. They are inclusion defects. It looks like there is slag inside the metal casting.

4. Sand Hole Defects

Sand hole is a typical shrinkage defect. After sandblasting or machining, you will see voids. The sand falls from the sand mold, rolls into the liquid metal, and creates blisters.

This is a problem of the sand mold, or the flow rate of the metal is too high. This decfect can be solved by the foundry.

5. Cold lap Defect

Also called cold shutdown. This is a crack with rounded edges. The cold lap is due to a lower melting temperature or a poor gate system. This is not just a surface defect. Generally, this location may cause air leakage, and in addition, the material at this location will be of poor quality and therefore may be fragile.

6. Flash, Fin and Burrs

The joint flash is also called a casting fin, which is a thin protrusion on the surface of a metal casting. During the cleaning and sanding process, the joint burrs should be removed.

Sharp fins and burrs are similar problems with burrs. In fact, the large flash is a casting problem, the foundry should improve it by modifying the pattern. However, the small fins and burrs are not casting defects, the foundry only needs to grind and remove them.

7. Mistrun defect

This is an incomplete casting defect, resulting in unfinished casting. The edges of the defect are rounded and smooth.

8. Porosity Shrinkage Defect

Shrinkage defects include scattered shrinkage, micro-shrinkage and porosity. For the large porosity on the surface, you can easily see them. However, for the smaller dispersion shrinkage, you can see them after processing. The figure below shows the shrinkage of porosity. The density of the metal is very poor, and many small holes can be seen after processing.

9. Shrinkage Cavities Defect

These are also called shrinkage cavities, which are a serious type of shrinkage defect, and you can easily see these holes on the rough surface of the metal casting. Foundries can improve their gates and ventilation systems, and then can solve these shrinkage problems.

10. Shrinkage Depression

This defect is also a type of shrinkage defect, which looks like a recessed area on the surface of a metal casting. Although this defect is not as serious as shrinkage, it still leads to poor surface quality, and there may be some internal defects, so the foundry should try to solve or improve it.

11. Elephant skin defects

This is a surface defect that can cause irregularities or wrinkles on the surface. This defect is caused by the temperature difference of the molten metal or poor sand mold.

12.Veins Defect

It is also called rat tail and looks like many small water traces on the surface of a metal casting. Sometimes this is caused by the low temperature of the molten metal or the improper gate control and exhaust system.

Veins Defect

13.Rough surface

A rough surface is also a surface defect. A normal rough surface cannot be considered a defect, but a surface that is too rough and uneven will be a defect.

Rough surface defects

14. Mismatch and displacement defects

This kind of mold defect is caused by the displacement of mold burrs. It will cause the parting line to be misplaced. Near the parting line, the left side may be a few millimeters lower or higher than the other side. The parting line is not a defect, but if the height on the left is different from the height on the right, it will be a casting defect. If there is no special requirement, a mismatch of less than 1mm is allowed. For the sand casting process, no mismatch is impossible.

However, if the mismatch affects the function of the casting, the foundry must control it, grind or machine it to meet the requirements.

Mismatch mold defects


15. Mechanical damage

This is not a casting defect, but a real casting quality problem you may encounter. This is damage during machining or delivery. Workers should pay more attention to this problem.

Mechanical damage defect

16.  Slag Inclusions Defects

This kind of defect is also called foreign inclusions, slag inclusions. Generally, slag is made of molten metal. During the metal melting process, the foundry should thoroughly remove dirt and inclusions, otherwise, these inclusions will be poured into the casting.

Slag inclusion defects

17. Raised Mold Defect

Due to the scattering of the liquid metal, the mold bottle is raised, causing the top of the casting to become higher or thicker than the lower part.

Raised Mold Defect

18. Crack defect

Crack defects usually occur inside metal castings. This defect will reduce the physical properties of the metal casting. There are also cracks on the surface.

Crack defect

19. Abnormal Nodulizing Defect

For many reasons, the spheroidization rate of graphite of ductile cast iron will be affected, resulting in poor spheroidization rate. Through the metallographic microscope, you can hardly see the graphite balls, but you can see many worm-like graphites.

This is a substantive issue. If so, its mechanical properties will not meet the standard requirements, which may cause damage to the cast product during use.

Abnormal Nodulizing Defect

20. Uneven hardness defects

This means that the hardness on the same surface is not uniform. The hardness is not uniform, and some parts may have extremely high hardness. When processing to a harder position, processing will become more difficult. The drill bit may be damaged.

This is a substantive issue. Locations with higher hardness may cool down faster than localized areas.

Uneven hardness

21. Sand Drop Defect

It is also called crushed sand. Some lumps of sand fall from the sand mold, which will result in similarly shaped sand holes or incompleteness. This is a problem of sand molds. The sand mold may not be tight enough.

Sand Drop Defect

22. Deformation problem

This problem will result in excessive flatness and straightness tolerances. For long castings and flat castings with thin walls, this is a very common defect. The reason is the natural deformation of the sand mold or the air during the cooling process. Sometimes, excessive sandblasting may also cause this problem.

Deformation problem

23. Welding Repair Problem

After welding repair, even after mechanical processing or polishing, welding traces are still visible. For unimportant casting surfaces, these marks should be acceptable if the customer allows welding repairs. However, for locations subject to high pressure, or the customer expressly prohibits any welding repairs, these marks will be considered defects.

24. Cold Iron Mark

Cast iron can effectively reduce the shrinkage of key parts, so it is very common to use cast iron in cast iron plants. However, the edges of the cold iron can be clearly found by visual inspection. If these marks do not affect the appearance, some customers will not need to grind them. However, customers may require the casting manufacturer to grind them in order to obtain a better surface appearance. Please be clear that these marks should not be considered as casting defects.

Cold Iron Mark

25. Casting chilling defects

It is also called “white iron”. The surface of the casting with this defect will be very white, shiny and smooth. Defective castings are fragile and brittle, so some edges and tips will break during processing. This defect is caused by the low temperature of the sand mold, and it leaves the sand mold prematurely, so the hot iron is quickly cooled. Appropriate annealing heat treatment on them can solve this defect.

26. Massive Free Carbide

On the metallographic photos, you can see many cemented carbides without fish bones. This is a serious defect of cast iron materials and usually occurs in ductile iron. Due to reverse cooling defects and poor inoculation, there will be qualityless carbides, which will lead to brittleness to ductile iron and poor welding performance. High temperature annealing heat treatment can improve its quality.

Massive Free Carbide

27. Cold short or short iron

This defect is also called internal sweating. There are iron beans in the casting. This is because of the unreasonable gate control design, causing some molten iron to suddenly become beans, and then these beans are wrapped in other molten iron. These are surface defects, but if they are located in critical locations, they can cause serious slurry problems.

Cold short iron

28. Stripping Defect

The iron sheet on the surface of the casting is very thin. Two floors. This is because the gating system is unreasonable, resulting in a very thin air layer. This defect is a surface defect, so it can usually be ground off. However, if it is not just on the surface, it should be discarded.

Stripping Defect

29. Cast Iron Graphite Floatation

This defect is a material problem. This is caused by low pouring temperature and high carbon content. This defect is very harmful and can lead to very fragile materials. On the fractured surface, you can see the obvious black surface caused by the defect.
