Carbon Steel
What is Carbon Steel??
Carbon steel is classified as a type of steel that is a mixture of iron and carbon. It has more carbon content, a lower melting point, and higher durability than stainless steel. Carbon steel is the preferred material for commercial engineering applications, including marine structures, energy plants, transportation, chemical processing and petroleum production and refining.
What are the types of Carbon steel?
The three basic types of carbon steel all have their own unique uses and features. The manner in which the carbon steel reacts with other elements determines its resistance to corrosion.
Low Carbon:
Low Carbon steel is also known as mild steel, it is the cheapest choice among cost-effectiveness, but it is also very bendable and can be modified into any shape, so it works perfectly for numerous applications.
Medium Carbon:
It has a significantly higher base carbon content than low carbon, and it has a bit more manganese element. Because of this, medium carbon is stronger than low carbon, but it may also be harder to work into shape due to strength and wear resistance. The same applies to its many uses, especially for machine and automotive parts.
High Carbon:
It is referred to as carbon tool steel, and stands out as the strongest steel you can buy. High carbon steel has a higher percentage of carbon than the other types. It could as well accommodate other elements to change the material’s properties. Chromium and manganese alloys can be added to high carbon steel, as it is being made, to assist the material steer clear of corrosion. High-carbon steel is also a good choice for polymer diffusion heat treatment to increase its hardness.
Carbon Steel Grades
| GRADE | TRAITS |
|---|---|
|
12L14 |
Free machining. Lead added to enhance machinability. Addition of lead does, however, reduce tensile strength, although it’s still generally stronger than 1018. Magnetic in all conditions. |
|
8620 |
Hard outer surface, combined with a ductile interior for higher strength.
|
|
A36 |
Chemically similar to 1018 but has inferior properties and rougher finish. Most commonly available of the hot-rolled steels. Yield strength also significantly less than 1018 |
|
A513 (alloy 1020-1026)
|
Its higher carbon content means higher strength, but lower weldability and machinability. |
|
1008 |
1008
Highest thermal conductivity among wrought plain carbon steels. Can have the lowest tensile strength and moderately high ductility. Excellent weldability.
|
|
C1010 |
Relatively low strength, but can be quenched and tempered to increase strength at a high cost. Fairly good machinability; good formability and ductility. |
|
C1018 |
Most commonly available cold-rolled steel. Has strength, some ductility, and comparative ease of machining. |
|
C1045 |
For applications in which more strength or higher hardness than that of 1008 or 1010 is required. |
|
C1141 |
For applications similar to those of 1045, but machinability is very important. |
|
C1144 |
Higher strength than 1018 or A36, but in addition has improved ductility. Very low distortion or warping after machining due to a combination of its chemistry, method of manufacture, and heat treatment. Relatively easy to machine.
