What is Carbon Steel Casting

Carbon steel castings (also called carbon steel investment casting) are mainly made of iron and carbon. Carbon steel is one of the main materials in the current cast steel industry. It has the advantages of low cost, high wear resistance, easy preparation, and can be heat treated to improve its strength, ductility, and processability.

Classification of carbon steel

Low carbon steel (<0.20% C):

Because of its low strength, low hardness, and softness, it is also called soft steel.

Medium carbon steel (0.20 to 0.50% C):

It is the most widely used material in various uses at medium strength levels. In addition to being used as a building material, it is also widely used in the manufacture of various mechanical parts.

High carbon steel (> 0.50% C):

After being properly heat-treated or hardened by cold drawing, high carbon steel has the advantages of high strength, high hardness, high elasticity, and not easy to deform.

 

Advantages of Carbon Steel Castings

  • Compared with other steels, carbon steel uses the largest amount and is easily obtained by casting.

  • Carbon steel can obtain higher hardness and better wear resistance after heat treatment.

  • The hardness in the annealed state is very moderate, and it also has good machinability.

  • The raw materials of carbon steel are very common, easy to obtain, and the cost of production is relatively low.

 

Carbon Steel Casting Process

There are currently two processes for carbon steel castings: water glass investment casting or silica sol investment casting

Water glass casting: Water glass is added to the molding material (commonly referred to as silica sand) according to a certain ratio, and it is made into "water glass sand" by stirring, rolling and mixing, and it is blown into the mold and sand box with CO2 gas, CO2 and water. The glass undergoes chemical reaction to form silica gel to harden the water glass sand, and is completed through the processes of mold lifting, box closing, and pouring.

Silica sol investment casting: This is a lost wax casting method. The mold is first made according to the shape of the silica sol cast part; the wax mold is placed in a solution made of silica sol and quartz sand. There will be a layer of material on the wax mold and then it will solidify. After repeated soaking and curing, it is basically formed. Finally, it is dewaxed and cast.

 

Application of Carbon Steel Castings

General mechanical parts:gears, connecting rods, hoods, etc. Ordinary hardware tools:wrenches, bucket teeth

The Most Common Questions, We Answer For You !
1. Can your factory produce stainless steel castings?
Yes,we can.we can do with stainless steel, carbon steel, alloy steel, high temperature nickel base alloy material.
2. Why your price is higher than other dewaxing foundry?
We are the casting of silica sol process, the best process in dewaxing casting. There are water glass process and composite process in dewaxing casting. The difference is that the quality of auxiliary materials is completely different, such as wax, glue, sand and so on.3. How accurate can your casting process be, or what tolerance level? Our silica sol casting process can achieve CT5-CT6 tolerance.
3. What is the weight range of castings you can make?
We can make 10g-80kg castings.
4. How long does your development time take?
For general structure products, we can complete the sample within 25 days from mold opening to sampling.
5. Where is your factory in China?
Our factory is located in Ningbo Zhejiang,the southeast of China, with a very developed transportation system.
6. Do you have existing molds that I can use?
This way I can save the cost of mold developing.
We are a non-standard custom factory and do not have our own molds. The existing more than 3,000 pairs of molds are owned by customers. We only store them on behalf of customers, so we cannot use customers' molds. If you need to develop products, you can only develop new molds.
7. Is your mold developed by your own factory?
We have our own ability to mold, but because of limited energy, we will develop both in our own workshop and outsourcing factory. We will also strictly review and verify the molds developed by the outsourcing factory, so we can be assured of the quality of the molds.
8. If the mold is developed, do I still need to invest in the mold cost during mass production?
Our products only need to be invested in the mold at the beginning. The subsequent molds can basically have a life of 500,000 times. Even if the product is made more than 500,000, we will develop new molds by ourselves and submit samples for your verification.No need to pay.
9. What is the general cost of developing molds?
The advantage of our casting process is the low development cost. For general structure products, the average mold fee is about 800USD.
10. What is the size and production capacity of your factory?
Our factory now has about 130 people, and the output value last year was 11 million USD. On the basis of the existing land and plant, there is still 50% of production capacity.
11. What is your payment method?
Our molds are generally 100% prepaid. If the product development does not meet the drawing requirements, we can refund 100%.
12. What industry are the products you are making now?
Our current products are distributed in a wide range of industries, including tools, construction hardware, pump valve bodies, auto parts, etc.
13. Do you have vacuum casting?
We have a vacuum casting production line that can make high-temperature nickel-based alloy products. Vacuum casting can reach the ultimate thickness of 0.5mm, but the thinnest non-vacuum casting is generally only 2.5mm.
14. Can you provide a test report for each batch of shipment? What are your testing equipment?
We can provide chemical composition report and size report every time. Our testing equipment includes Spike brand spectrometer and Hexagon brand three-coordinates. For details, please see our testing equipment page.
15. How long is your delivery date?
Our delivery time for goods is generally around 45 days. If you have urgent orders that need to be processed, we can help you make them expeditiously within 15 days.
