What is carbon steel? Why add carbon to iron? It strengthens the metal by solidifying its internal structure. Carbon is also one of the cheapest alloys and has a wide range of applications.

What Is Carbon Steel

What Is Carbon Steel Type

Each type of carbon steel has its own unique applications and characteristics. This type of steel is divided into three distinct categories- High Carbon Steel / Medium Carbon Steel / Low Carbon Steel. You need to determine which one is more suitable for your needs.

To help you make a more informed project choice, The steel variety of carbon steel, their carbon content, microstructure and properties compare as follows.

High Carbon Steel vs Low Carbon Steel

What is carbon steel advantages and disadvantages?

In the carbon steel category, there are two sub-groups of high carbon steel (carbon content 0.60% or higher) and low carbon steel (carbon content not exceeding 0.30%). The advantages of high carbon steel can be widely used in the construction field include the following aspects:

  • The intensity. The greatest advantage of carbon steel is its durability. It is strong and impact-resistant, which is why it makes such a beneficial material for construction projects.
  • Sustainability. Carbon steel is sustainable and easy to recycle and reuse.
  • Affordability. It is much cheaper to make certain products from carbon steel than other metals because a little goes a long way. Its durability means that less metal can be used while still performing the same functions as materials that might be made of other metals such as copper, such as pipes.
  • Security. Handling steel is relatively easy and safe. It is also commonly used in cookware because it does not release potentially harmful chemicals into food.

Performance of Carbon Steel

Let’s take a look at what high carbon steel is, what carbon steel is made of, what mild steel is, and the composition of carbon steel!

Low-carbon steel, has the widest selection of shapes, from plates to structural beams.

Medium-carbon steel is stronger than low carbon steel, but it is more difficult to form, weld and cut. It is usually hardened and tempered by heat treatment.

High-carbon steel also known as carbon tool steel, is difficult to cut, bend and weld. After heat treatment, it becomes very hard and extremely brittle.

Forging Temperature of Csrbon Steel

The temperature at which the steel is heated before it is deformed or formed by hammering, compression or rolling is particularly critical to ensure that the steel can be effectively shaped, avoid cracks and other defects, and ensure that the finished product meets predetermined strength and toughness standards.

Carbon Steel Application

Carbon fiber steel pipe has been widely used in many industries, covering many fields such as industrial and civil:

  • Building and construction: It serves both as a supporting column for the building and as a key component of the bridge, and as a pipeline for the supply and discharge of water.
  • Manufacturing: It is used in the manufacture of mechanical parts, automotive parts and the production of various tools.
  • Oil and gas industry: carbon steel pipes dominate the pipe selection for oil drilling and gas transmission media.
  • Energy industry: involves power plants, nuclear power stations and renewable energy projects, mainly for steam and water transmission processes.

FAQs:

1. Is carbon steel better than stainless steel?

Compared with low-carbon steel stainless steel has a great improvement in strength hardness and most importantly corrosion resistance. The strength of high-carbon steel is comparable to and sometimes even exceeds stainless steel but it is mainly a niche material in the manufacturing industry.For more information, please click the link below.

2. What is the difference between steel and carbon steel?

Compared with low carbon steel, carbon steel has obvious advantages in terms of strength properties. It is 20% stronger than low carbon steel, which is why carbon steel can be widely used in high-strength projects, but the cost of carbon steel will be higher.

3. What does carbon do to steel?

When added to iron to make steel carbon affects its mechanical properties including hardness strength and toughness. It also affects the heat treatment capacity workability and reaction to welding of steel. The balance between carbon content and other alloying elements is critical to the design of steel alloys for specific applications.
