1018 Steel vs A36 Steel – What’s the Difference

1018 Steel vs A36 Steel

Steel is an incredibly popular material used in construction, manufacturing, and various other industries. However, the properties and qualities of different steel types can significantly impact their performance. Two of the most commonly used types of steel are 1018 and A36. In this blog, we’ll take a closer look at these two types of steel, their properties and applications, and their key differences.

Difference Between 1018 Steel and A36 Steel

Chemical Composition:

The chemical composition is the most significant difference between 1018 and A36 steel. 1018 steel is low-carbon steel, while A36 steel contains higher levels of carbon. As a result, A36 steel is generally considered harder and more durable, while 1018 steel is softer and more easily machinable.

Tensile strength:

Another key difference between these two types of steel is their tensile strength. A36 steel has a higher tensile strength than 1018 steel, making it more suitable for high-stress applications. However, this also means that A36 steel is more brittle, which can increase the risk of cracking or breaking under extreme pressure.


Both 1018 and A36 steel are used in various applications. 1018 steel is commonly used in construction, manufacturing, and engineering, where its machinability and low cost make it an attractive option. A36 steel is also used in these industries but is more commonly found in manufacturing heavy equipment, machinery, and vehicles due to its higher tensile strength.


The cost of both 1018 and A36 steel can vary depending on a variety of factors, including the supplier, the quantity purchased, and the market demand. However, in general, 1018 steel is significantly cheaper than A36 steel. This makes 1018 steel a more attractive option for many applications, particularly in industries where cost is a major factor.


Finally, the machinability of 1018 steel is one of its most significant advantages. Thanks to its low carbon content, 1018 steel is easy to manipulate and machine, making it a popular choice for manufacturing processes requiring high precision and customisation. A36 steel, on the other hand, is more difficult to machine due to its higher carbon content.


In conclusion, understanding the differences between 1018 steel and A36 steel is crucial for anyone working in industries that rely on steel. While both types of steel have their advantages and disadvantages, the decision of which one to use depends on the specific requirements of the project at hand. Whether you’re looking for a cost-effective option for construction or a more robust material for heavy machinery, there’s a type of steel that will suit your needs.
