1008 Steel vs 1018 Steel – What’s the Difference

1008 Steel vs 1018 Steel

If you are in the market to buy steel, you have probably come across two types of steel, 1008 and 1018. While they may look similar, significant differences make them better suited for specific applications. In this blog post, we will closely examine these two types of steel and what distinguishes them.

Difference Between 1008 Steel and 1018 Steel

Chemical Composition:

The primary difference between these two steels lies in their chemical composition. 1008 steel has a lower carbon content than 1018 steel. 1008 steel also contains no more than 0.10% sulfur and 0.025% phosphorus. 1018 steel has slightly higher percentages of carbon, sulfur, and phosphorus.


Due to its lower carbon content, 1008 steel is softer and easier to machine but also weaker than 1018 steel. 1018 steel, on the other hand, is harder and stronger than 1008 steel. This makes 1018 steel better suited for higher strength and durability applications.


Weldability is one of the essential considerations when selecting a steel grade. 1008 steel is more weldable than 1018 steel because it contains lower carbon content. 1018 steel has a higher carbon content, making welding more challenging. If you need a steel that is easy to weld, 1008 steel may be a better option.


The price of each steel type varies depending on the supplier and the market conditions. However, in general, 1008 steel is less expensive than 1018 steel. Due to its softer and more machinable properties, 1008 steel requires less energy, making it less expensive.


1008 steel is commonly used in manufacturing automotive parts, such as hoods, fenders, and doors. It is also used in appliances, construction, and low-pressure fluid handling. 1018 steel is suitable for applications that require higher strength, such as gears, shafts, pins, and axles. It is also used to construct large structures, such as buildings and bridges.


In conclusion, the difference between 1008 and 1018 steel lies in their chemical composition, strength, weldability, cost, and applications. These steel types have unique properties that make them better suited for specific applications. It is essential to consider these factors when selecting the right steel type for your project. Understanding the differences between these two types of steel can help you make an informed decision when shopping for steel.
