Mild Steel vs Tor Steel – What’s the Difference?

Mild Steel vs Tor Steel

Choosing the right type of steel for a job is essential for ensuring safety and durability. Steel is an alloy composed of iron and carbon, and its properties depend on the composition of the alloy and how it is processed. Two common types of steel used in construction and engineering are mild steel and tor steel. These steels have different properties and are used for different applications. In this blog post, we will discuss the differences between mild steel and tor steel and how to choose the right type of steel for your project.

What is Mild Steel?

Mild Steel is a type of low-carbon steel which contains between 0.05 % and 0.3% carbon, making it relatively strong and ductile compared to other types of steel. Due to its malleability and cost-effectiveness, it is widely used for manufacturing products such as automotive parts, building construction materials, tools and general engineering applications.

What is Tor Steel?

Tor Steel is an alloy of carbon, manganese and other elements. It has high strength, hardness, excellent corrosion resistance, and ductility. Tor steel also possesses good fatigue resistance and toughness. It can be used in structural applications such as bridges, buildings, towers, boats…etc.

Difference Between Mild Steel and Tor Steel

Mild steel is a ferrous alloy with low carbon levels and up to 0.25% carbon. In comparison, tor steel is high-strength structural steel containing 0.3–0.6% carbon with even higher tensile strength than mild steel due to its quenching and tempering process during manufacturing.

Composition and Properties

Mild steel is an alloy of iron and a small amount of carbon (less than 0.25%). It is also called low-carbon steel, which is easy to weld and form into various shapes. Mild steel has a high tensile strength and is suitable for structural applications such as beams, columns, and plates. It is also used for making pipes, tanks, and storage containers.

On the other hand, tor steel is a type of high-strength deformed steel bar that contains a higher percentage of carbon (up to 0.6%) and other elements, such as chromium, copper, and nickel. These elements increase the tensile strength of the steel and make it more resistant to corrosion and high temperatures. Tor steel is commonly used in reinforced concrete structures, such as pillars, beams, and slabs, to provide strength and stability.

Manufacturing Process

Mild steel is produced by mixing iron and carbon in a furnace and then rolling the molten metal into flat sheets or bars. The metal is cooled slowly to improve its strength and other mechanical properties. Tor steel, on the other hand, is made by heating the metal to a higher temperature and then passing it through a series of rollers to deform it into a ribbed or corrugated shape. This process increases the surface area of the steel and provides better adhesion to the concrete.

Cost and Availability

Mild steel is generally cheaper and more readily available than tor steel because it is a more basic form of steel. Mild steel can be sourced from local suppliers, while tor steel may need to be imported or specially ordered. The cost of steel also depends on the grade and thickness of the metal and the purchase volume.

Application and Suitability

The choice of steel depends on the specific requirements of the project and the environment in which it will be installed. Mild steel is suitable for most structural applications, where strength and durability are required but not at a very high level. It can be easily welded, cut, and shaped into various forms. Tor steel is ideal for reinforced concrete structures requiring higher strength, corrosion, and fire resistance. It is also used in high-rise buildings, bridges, and heavy machines.


In conclusion, mild steel and tor steel are two different types of steel used in construction and engineering. Mild steel is a low-carbon steel suitable for most structural applications, while tor steel is a high-strength deformed steel bar used in reinforced concrete structures. Choosing the right type of steel depends on the specific requirements of the project and the environment in which it will be installed. Both types of steel have advantages and disadvantages, and consulting with a steel expert can help you make an informed decision.
