Low Carbon Steel vs Mild Steel – What’s the Difference?

When it comes to steel, there are various types available in the market. Each type is designed for a specific application. However, many use “low carbon steel” and “mild steel” interchangeably. In this blog post, we’ll explain the difference between these two types of steel and their unique features.

Difference between Low Carbon Steel and Mild Steel

First, let’s talk about low-carbon steel. This type of steel is known as “mild steel” or “plain carbon steel” and contains carbon content between 0.04% to 0.3%. Low-carbon steel is highly machinable, weldable, and formable, making it an ideal material for construction, manufacturing, and structural applications. It is also the most common type of steel used in various industries. Low-carbon steel is relatively cheap and has excellent ductility and toughness, making it easy to shape into various products.

On the other hand, mild steel is a generic term used to describe different types of steel alloys that have low carbon content. Typically, mild steel contains a carbon content between 0.05% to 0.25%. Mild steel is more robust and has superior strength than low-carbon steel. Mild steel is commonly used in making automotive parts, pipelines, and structural applications such as bridges. It also has an attractive finish when coated with paint.

Low carbon steel vs mild steel: There are a few differences between the two types of steel that you need to know about. Firstly, low-carbon steel has better ductility, which means it can be shaped and formed into different shapes more easily than mild steel. Secondly, mild steel has more significant tensile strength and is used for making automobile parts, pipelines, etc. Finally, although they both have low carbon content, it is easier to weld low-carbon steel than mild steel.

Another critical difference between low-carbon and mild steel is their properties when subjected to heat treatment. Heat treatment can harden low-carbon steel, while mild steel cannot. Heat treatment is when the steel is heated to an optimal temperature and then cooled rapidly to alter its physical properties, such as its hardness, strength, and ductility. Low-carbon steel can endure heat treatments, which improves its hardness and tensile strength. For More information visit marketsmartb2b


In summary, low-carbon steel is highly machinable and weldable, while mild steel is stronger and has a higher tensile strength. Both are designed for specific applications, and it is essential to understand their differences when choosing the right steel for your needs. Low-carbon steel is the best choice if you need machinable and formable steel. If you need stronger and more robust steel, then mild steel is your choice. Choosing the right steel for your specific application is crucial to ensure its durability, performance, and safety.
