1144 Steel vs 1045 – What’s the Difference

1144 steel vs 1045

The selection of the right steel is a crucial aspect of any project, and it depends on different factors such as performance, strength, and machinability. Therefore, it is vital to know the differences between various types of steel and choose the right one for your project. This post will compare two popular steel options: 1144 steel and 1045 steel. We will explore the properties and applications of each steel type to help you make an informed decision for your project needs.

What is 1144 Steel?

1144 steel is a desulfurized steel with a higher sulfur content than 1045 steel. This gives it better machinability but reduced weldability. It also has a higher carbon content, which gives it a higher hardness and strength.

What is 1045 Steel?

1045 steel is non-desulfurized steel with a lower sulfur content than 1144 steel. This gives it poorer machinability but improved weldability. It also has a lower carbon content, which gives it a lower hardness and strength.

Difference Between 1144 Steel and 1045


1144 steel and 1045 steel are carbon steels with a high carbon content. This gives them both a high strength and a high wear resistance. However, they differ in other properties, such as hardness, flexibility, and toughness.

Comparison of Properties

The table below shows the properties of 1144 steel and 1045 steel:


1144 Steel is typically used in applications where strength and wear resistance are important, such as gears, shafts, and fasteners. 1045 steel, such as pipes and structural applications, is typically used when weldability is important.


Both 1144 steel and 1045 steel have distinct properties and applications that make them suitable for different projects. The choice between these steels depends on strength, durability, machinability, and heat treatment. Ultimately, the final selection must be made by considering the specific requirements of your project. Therefore, consulting with a steel supplier or expert is essential to help choose the right steel for your project needs.
