1019 vs 1018 Steel – What’s the Difference

1019 vs 1018 Steel

Steel is one of the most widely used materials in the industrial sector due to its strength and durability. Two types of steel that are often compared are 1019 and 1018 steel. These steels belong to the carbon steel family and are widely used in various applications. However, they do have their differences which can impact their performance in certain applications. This blog post will explore the differences between 1019 and 1018 steel to help you understand which is best suited for your application.

Difference Between 1019 and 1018 Steel

Chemical Composition

The chemical composition of 1018 and 1019 steel vary slightly. 1018 steel contains 0.18% carbon and 0.6-0.9% manganese, whereas 1019 steel contains 0.19% carbon and 0.6-0.9% manganese. While the difference in carbon content seems minimal, it can impact the steel’s properties. 1019 steel has a slightly higher carbon content than 1018 steel, which makes it stronger and more wear-resistant.


Both of these steels have good machinability and can be easily welded. However, 1018 steel has better machinability than 1019 steel. It is softer and easier to work with, which makes it ideal for applications that require a lot of cutting, drilling, or milling. 1019 steel, on the other hand, is harder, which means it can be more difficult to machine.


1019 steel is stronger than 1018 steel. Due to its higher carbon content, it offers better strength and toughness properties. If you require steel that can handle heavy loads, 1019 steel might be a better option. However, if you are looking for a steel that is easier to work with and machinable, 1018 steel offers a good balance of strength and machinability.


Cost is an important factor when choosing between 1018 and 1019 steel. 1018 steel is less expensive than 1019 steel and is widely available. If your budget is limited and you do not require high-strength properties, 1018 steel might be a cost-effective option. 1019 steel, on the other hand, is more expensive due to its higher strength and wear-resistant properties.


Both 1018 and 1019 steel are used in a variety of applications. 1018 steel is commonly used in bolts, nuts, screws, gears, and shafts. It is also used in the construction industry for making structures such as bridges and buildings. 1019 steel, on the other hand, is commonly used in high-stress applications such as axles, crankshafts, and machinery parts.

Advantages of 1019 Steel

The advantages of using 1019 steel include its low cost, ease of machining, and ability to be welded. Additionally, 1019 steel can be heat treated to create various strength levels, making it a versatile option for multiple applications.

Advantages of 1018 Steel

The advantages of using 1018 steel include its high strength, flexibility, and ability to be heat treated. Additionally, 1018 steel can be easily welded and formed into various shapes.

Disadvantages of 1019 Steel

The disadvantages of using 1019 steel include its lower strength and flexibility when compared to 1018 steel. Additionally, because it is low-carbon steel, it is not as resistant to wear and tear as other types of steel.

Disadvantages of 1018 Steel

The disadvantages of using 1018 steel include its higher cost when compared to 1019 steel. Additionally, because it is high-carbon steel, it can be difficult to weld and susceptible to cracking.


In conclusion, both 1018 and 1019 steel have their advantages and disadvantages. 1018 steel is easier to work with, machinable, cost-effective, but less strong than 1019 steel. 1019 steel, on the other hand, is stronger and more wear-resistant but harder to machine and more expensive. When choosing between the two, it is important to consider your application requirements, budget, and manufacturing process. We hope this blog post has given you a better understanding of the differences between these two types of steel and which one might be best suited for your needs.
