One of the comments we received from our respected readers in the material selection is that there are just too many varieties of steel that can be utilized in industrial production, and it can be challenging to distinguish between the different steels’ advantages and disadvantages.
1018 is a great example. It is a low carbon structure steel with good mechanical and processing properties as well as pervasiveness in industrial applications, but still hard for many people to distinguish it from other materials.
This article will guide you its definition, properties, pros and cons, and uses in industriai manufacturing.
What is 1018 Steel?
At the start of this article, I’ll introduce our esteemed reader about 1018 steel’s basic attributions, physical and chemical composition and brief history.
Brief Overview of 1018 Steel
1018 steel is a popular type of carbon alloy steel that is known for its excellent welding and forming capabilities.
It is also commonly referred to as low-carbon steel due to its relatively low carbon content compared to other types of steel.
This grade of steel is often used in a variety of applications, including machining, automotive parts, construction equipment, and more.
Physical and Chemical Composition
The composition of this steel grade plays a significant role in its overall performance in various applications.
| Physical and Chemical Composition |
| Primary Elements | Iron and Carbon |
| Other Elements Contained With Minor Amount |
|
| Density | Around 7.85 g/cm³ |
| Specific Gravity | 7.9 |
| Melting Point |
1425-1540°C |
| Thermal Conductivity | 49.8 W/mK |
Brief History of 1018 Steel
Origins of 1018 steel can be traced back to the early 20th century when the American Iron and Steel Institute (AISI) designated it as a standard steel grade for industrial applications.
With the evolution of technology, the manufacturing process has become more efficient and precise.
Innovative techniques such as computer-aided design (CAD) and computer numerical control (CNC) machining have revolutionized the production of related parts.
Mechanical Properties of 1018 Steel
By this part, we’ll see what advantages 1018 steel offers, its weakness and limitations, and what makes it different from other alloy.
Advantages in Physical Properties
Strength and Ductility: This type of steel is commonly used in applications where strength is required, such as in the construction of buildings, bridges, and machinery.
Weldability and Machinability: Like other carbon steel has excellent weldability, 1018 is allowed to create complex and precise shapes in welding processes without sacrificing strength, especially in constructing structures that requires greater tensile strength.
Good machinability also makes it can be easily turned, drilled, and milled with minimal difficulty and ideal for small parts and components that require precision machining.
Formability: Good formability allows it to be easily shaped into different forms without cracking or breaking, makes it a preferred choice for manufacturers who require a material that can be easily manipulated into various shapes and sizes.
What Limits the Steel 1018
Low tensile strength: It’s tensile and yield strength is not suitable for heavy and tough loads.
This can limit its lifespan and require more frequent maintenance and upkeep to prevent deterioration, especially to wear and tear.
Low hardness: Reduce carbon content has its own negatice effect on hardness.
Compare with other steels with higher carbon content, 1018 is more prone to wear and tear in high-friction applications, results in shorter tool life and increased costs for replacement and repairs.
High operation requirements: It is not as easily machinable as some other steels, which can make it more difficult and time-consuming to work with in manufacturing processes.
High protection requirement: The corrosion resistence requires proper protection and maintenance to keep.
Without the protection, It will becomes susceptibility to corrosion, rust and deteriorate very soon.
Differences with Other Iron and Carbon Steels
When comes to 1018 steel comparison with other carbon steels, there are a few key differences to take note of.
Carbon content: 1018 steel is a mild steel, which is characterized by its low carbon percentage compared to other higher carbon content steels, makes it easier to weld and form.
This lower carbon content also gives it a smoother surface finish and better manufacturing control.
Manganese: 1018 is high-manganese carbon alloy compare with other carbon steels, which can improve the hardenability of the steel and provide better strength and durability.
Heat Treatment Process: 1018 is typically annealed, which can help improve its durability and toughness.
This makes it a good choice for parts that require a combination of strength and flexibility.
