Dawang Produces Precision Carbon Steel Components

Dandong Dawang Steel Castings provides advanced carbon steel and low alloy castings for demanding modern industries. We produce precision components and accurate parts with industry-leading tolerances and desirable mechanical properties. Carbon steel offers a range of benefits in an economical package, making it a popular material for investment casting.

What is Carbon Steel Casting?

When a material is an alloy of carbon and iron, it is considered carbon steel. There is no minimum content requirement for other elements (such as manganese, vanadium, nickel, or copper). Generally, the carbon content in the composition of this alloy is less than 2%, and it usually varies between 0.1% and 0.9%.

Low carbon steel castings


As you can see, low carbon steel has a low carbon content. It is known for ductility, weldability, and machinability. Therefore, low carbon steel castings are softer than other steels, have low tensile strength, and are not suitable for heat treatment. We commonly use carbon steel castings in the automotive and construction industries, including fasteners, bolts, shafts, rods, pins, components, etc.

Dawang provides the following carbon steel investment casting:

4140 carbon steel
8620 carbon steel
4130 carbon steel
4340 carbon steel
6150 carbon steel

Medium carbon steel castings


Likewise, medium carbon steel contains a moderate level of carbon content and is known for its wear resistance. It is harder than low-carbon steel and can be strengthened by heat treatment. Therefore, we commonly use medium carbon steel investment casting in military and defense applications, including engine parts, couplings, crankshafts, aircraft tubing, and guns.

Dawang casts a series of medium carbon steel castings, including:

1020 carbon steel
52100 carbon steel
1010 carbon steel
1040 carbon steel

High carbon steel castings


As above, the carbon content of high carbon steel is 0.55-0.95%. High carbon steel has high strength and good shape memory, making it a beneficial choice for spring manufacturers. In addition, this alloy steel for high-strength applications can withstand wear and is also suitable for heavy-duty applications such as cranks and pins.

Dawang provides the following high carbon steel casting:

1095 high carbon steel
1060 high carbon steel
1080 high carbon steel

How are carbon steel castings made?

steel casting grades
Carbon steel is one of the most popular metal manufacturing materials. But how are carbon steel castings made, and what makes it such a reliable choice in the modern industry? Due to a large amount of available data, it becomes easy to predict its behavior under real-world conditions. That is to say, this kind of reliability is the core of the versatility of carbon steel castings. By selecting established ingredients, engineers can model the behavior of the metal during its expected life cycle.
To make reasonable predictions, the manufacturing of carbon steel castings must be consistent throughout the production process. In fact, as one of the most commonly used metals on earth (carbon steel is the leading promoter of the industrial revolution), the manufacturing process of carbon steel castings has been mature and highly automated. Just as any engineer will tell you, and good data means good data output.

Carbon Steel Casting Grades

To make your assessment easier, we’ve compiled a carbon steel casting grades chart highlighting the most commonly used carbon steel grades and their applications.

Use the information below to obtain the correct carbon steel casting grades for your project.

Benefits of Carbon Steel Castings

As we all know, carbon steel is much cheaper than stainless steel, and it is durable. On the one hand, carbon steel castings are easy to obtain and can be combined with one or more alloying elements to make them easy to customize. On the other hand, carbon steel castings can be made very thin. So we can reduce costs by using less material.

Four Benefits of Carbon Steel Casting

Carbon steel casting applications are endless. They serve the automotive, railway, heavy equipment industries, and more. 

Carbon steel is beneficial for motor and electrical appliances due to its ferromagnetic properties. It is a safe, durable alloy with a high level of structural integrity;

All features contribute to it being one of the most popular alloys in the world. Steel is also one of the most recycled materials globally, making it an attractive material for companies with sustainable goals. 

There are several benefits to utilizing carbon steel casting and low alloy steel casting. Still, the following four advantages of carbon steel casting apply to industries that are looking for cost-effective materials without sacrificing quality and durability:

  • Cost-effective mechanical parts
  • Multiple material grades to fit any application
  • End of life recyclability
  • High structural integrity

What are the benefits of carbon steel castings for your business?

Above all, carbon steel castings are strong, durable, and have the perfect composition for most jobs. We can efficiently process mild steel into any imaginable shape or specification. 

Moreover, steel alloys with higher carbon content can provide you with the hardness to perform more complicated tasks. If your commercial, industrial or residential projects require prefabricated metal, carbon steel castings can meet your needs.
