12L14 vs Low Carbon Steel – What’s the Difference

12L14 vs Low Carbon Steel

Choosing the correct type of steel for your project can take time to know where to start. With so many different types available, it’s essential to understand their differences to make an informed decision. In this blog post, we’ll be discussing the differences between 12L14 and low-carbon steel.

Difference Between 12L14 and Low Carbon Steel


While both 12L14 and low carbon steel are types of carbon steel, their composition sets them apart. 12L14 steel contains lead, a lubricant during machining, making it ideal for threaded parts and bushings. On the other hand, low-carbon steel has a lower carbon content, making it easier to weld and form than different types of steel.


One of the significant differences between 12L14 and low-carbon steel is their machinability. 12L14 is much easier to machine due to its lead content, which acts as a lubricant, reducing friction. Low-carbon steel, while still machinable, requires more effort due to its higher carbon content.


When it comes to weldability, low-carbon steel is the better option. Its lower carbon content makes it less likely to become brittle during welding. Welding 12L14 steel can result in porosity due to the lead content.


While 12L14 steel is more accessible to machines, it’s weaker than low-carbon steel. Low-carbon steel has a higher tensile strength, making it a better option for structural applications.


When choosing between 12L14 and low-carbon steel, the cost may be a factor to consider. 12L14 steel is more expensive than low-carbon steel due to its lead content and ease of use during machining.


In conclusion, when choosing between 12L14 and low-carbon steel, it’s essential to consider the project’s requirements. If you need to machine parts with threaded holes or bushings, 12L14 steel may be the better option. Low-carbon steel is the better choice for applications requiring strength and weldability. Remember that cost can also play a factor in the decision-making process. Understanding the differences between these two types of steel will help you make an informed decision for your next project.
