1215 Steel vs 1018 – What’s the Difference

1215 Steel vs 1018

Steel is one of the most widely used materials in many manufacturing applications. It is strong, durable, and versatile, making it an ideal option for many projects. When choosing the right type of steel, many options are available on the market. Two of the most popular types are 1215 steel and 1018 steel. These steels have unique properties, making them suitable for different projects. This blog post will discuss the differences between 1215 and 1018 steel and which one you should choose for your project.

Difference Between 1215 Steel and 1018


The main difference between 1215 steel and 1018 steel is their composition. 1215 steel contains more sulfur and phosphorus, which makes it easier to cut and machine. This type of steel is also known as “free machining steel” because of its high machinability. On the other hand, 1018 steel has a lower sulfur and phosphorus level, making it more difficult to machine.


When it comes to strength, both 1215 steel and 1018 steel are similar. They have similar tensile strengths, meaning they can withstand similar stress levels without breaking. However, 1215 steel has a slightly lower yield strength than 1018 steel, so that it will deform more easily under stress.

Corrosion Resistance

Another important factor to consider when choosing between 1215 and 1018 steel is their corrosion resistance. 1215 steel is more prone to corrosion than 1018 steel, which requires more frequent maintenance to prevent rust and other forms of corrosion.


Both 1215 and 1018 steel are easily weldable but require different welding methods. 1215 steel requires low-carbon electrodes, while 1018 steel requires high-carbon electrodes. This means that the welding method will depend on the type of steel you choose for your project.


The cost is the final factor when choosing between 1215 and 1018 steel. 1215 steel is generally cheaper than 1018 steel because it is easier to machine and has lower labour costs. However, the cost also depends on the overall size of the project and the amount of steel needed.


In conclusion, choosing between 1215 and 1018 steel will depend on your specific project requirements. If you need steel that is easy to machine and has high machinability, then 1215 steel is the ideal option. However, if you require steel with better rust resistance, higher yield strength, and more deformation resistance, then 1018 steel is the better choice. Ultimately, you should consult a professional steel supplier or manufacturer to determine which type of steel would best suit your project.
