Types of Mild Steel

Types of Mild Steel

There are several types of mild steel, including:

Low Carbon Steel:


This type of mild steel has a carbon content of less than 0.25%. It is also known as “mild steel” because of its low strength and hardness.


Medium Carbon Steel:

This type of mild steel has a carbon content between 0.25% and 0.60%. It is stronger and harder than low carbon steel, but still considered mild steel.


High Carbon Steel:

This type of mild steel has a carbon content between 0.60% and 1.25%. It is harder and stronger than medium carbon steel, but still considered mild steel.


Ultra-High Carbon Steel:

This type of mild steel has a carbon content greater than 1.25%. It is the hardest and strongest type of mild steel.


Cold Rolled Steel:

Cold-rolled steel is a type of mild steel that is used in various industries for different applications. It is produced by rolling steel at a low temperature and is known for its improved strength, durability and surface finish.


Hot Rolled Steel:

This type of mild steel is made by rolling steel at a high temperature. It is known for its excellent formability and weldability.

Galvanized Steel:

This type of mild steel is coated with a layer of zinc to protect it from corrosion. This process is known as galvanization. Galvanized steel is commonly used in construction, automotive, and other industries where corrosion resistance is important.

Electro-Galvanized Steel:

This type of mild steel is also coated with zinc, but the process is done through electroplating. This method is more precise and can produce a thinner and more consistent zinc coating than hot-dip galvanization.

Structural Steel:

This type of mild steel is used in construction and engineering applications. It is characterized by its high strength and low alloy content, and is commonly used in the construction of buildings, bridges, and other structures.

High-Strength Low-Alloy Steel (HSLA):

This type of mild steel is a variation of structural steel with added alloying elements such as chromium, nickel, and molybdenum. The added alloying elements increase the strength and toughness of the steel without significantly increasing its weight.

Pickled and Oiled Steel:

This type of mild steel is cleaned using a process called pickling to remove surface impurities and then coated with oil to protect it from rust. This process improves the steel’s surface finish and makes it easier to work with in manufacturing and fabrication processes.

Floor Plate Steel:

This type of mild steel is a variation of hot-rolled steel with a raised diamond pattern on one side, which provides a non-slip surface. It is commonly used in construction, industrial and transportation applications.
