Mild steel is a type of carbon steel that has low carbon content, typically between 0.05% and 0.25% by weight. It is also known as low carbon steel or plain carbon steel. The low carbon content in mild steel makes it relatively soft and malleable, which means it can be easily formed, welded, and machined into various shapes.

Mild steel is one of the most commonly used materials in construction, manufacturing, and other industries because of its versatility and affordability. It is used to make a wide range of products, including structural steel, pipes, sheets, plates, and wires.

One of the key properties of mild steel is its strength. While it is not as strong as high carbon steel or other alloys, it is still strong enough for most applications. Mild steel also has good ductility, which means it can be deformed without cracking or breaking.

Mild steel can be further classified based on its carbon content, which can range from ultra-low (less than 0.02% carbon) to high (up to 2.1% carbon). The different grades of mild steel have varying properties and are used for different applications.

Overall, mild steel is a popular choice for many applications because it is affordable, easy to work with, and can be used for a wide range of products.
