What are mild steel ?

Steel that is mild contains a very low level of carbon, which makes it one of the most commonly used carbon steels. Otherwise known as low carbon steel, mild steel contains roughly 0.05% to 0.25 percent carbon by weight. As opposed to high carbon steel, which can consist of up to a 25% carbon content by weight, mild steel does not contain a lot of other elements in addition to iron and ferrite. As a result, mild steel is not an alloy steel.

What are high tensile steel?

Among the low carbon steels, high-tensile steels are part of a group of alloying ingredients that include chromium, molybdenum, silicon, manganese, nickel, and vanadium. With these additions, high-tensile steels can be designed to increase both their durability, as well as their malleability and ductility.

What is the Difference Between Mild Steel and High Tensile Steel?

Among the many types of carbon steel, mild steel has a low carbon content by weight, while high tensile steel has a high yield strength and tensile strength. It is a type of mild carbon steel that has a very low carbon content by weight. The main difference between mild steel and high tensile steel is that high tensile steel has a much higher strength than mild steel. Compared to many forms of mild steel, high tensile steel shows a lower plastic ductility and brittle fracture than other steel types. High tensile steel has a higher carbon content compared to mild steel, which explains its higher strength.

Mild Steel


One of the most important features of mild steel is that it is not fragile. Furthermore, it does not require tempering readily and has excellent quality. It is also a very good electrical conductor. Because mild steel is ferromagnetic in nature, it has high malleability which enables it to be used in welding. This is because mild steel has a low carbon content. Therefore, mild steel can be magnetized very easily due to its ferromagnetic properties.

Furthermore, this material can be used for structural purposes. This material has a higher carbon content than low carbon steel, which makes it more susceptible to erosion than low carbon steel. High tensile steel is a kind of mild carbon steel with a high yield strength and tensile strength. To build the steel’s tensile strength, it contains distinctive alloying components. Chromium, silicon, manganese, nickel, molybdenum, and vanadium are some of the most important components that will be used for specific purposes such as making parts for automobiles, making crane ropes, and so on.


The Carbon Steel is a type of steel that is unalloyed, and it contains components such as carbon, sulphur, manganese, phosphorus, and silicon. Mild steel is a type of carbon steel that contains between 0.15 and 0.25 percent of carbon by weight. The carbon content of high tensile steel varies between 0.60 – 0.80%, Sulphur 0.05%, Manganese 0.60%, Silicon 0.20%, and Phosphorus 0.05%.


There is a difference between mild steel and high tensile steel in terms of its ability to resist force, weight, or stress. Mild steel has less strength than high tensile steel.


There are many applications for mild steel, including moving areas, reinforcing bars, roof coverings, sheet piles, and so on. High Tensile Steel is used as a pretensioning or posttensioning agent for prestressed concrete constructions. There are many kinds of liftings, including atomic reactors, hoisting, and pulling hydropower plants and nuclear power plants.

High Tensile Steel


There is a feature in material flexibility that is characterized by the ability to bend, bend, hammer or press metal into the desired shape. Mild steel is more malleable than high tensile steel when it comes to bending, hammering or pressing.

There are two types of carbon steel structures, mild steel and high tensile steel. High tensile steel, however, is a type of mild steel, since both contain very little carbon. It is important to know that the main difference between mild steel and high tensile steel is that high tensile steel is much stronger than mild steel. However, they are going to be used in a wide variety of different applications based on their distinctive features. But the increase in the percentage of carbon correspondingly decreases elasticity, flexibility, and durability. The article clarifies the difference between Mild Steel with low carbon and High Tensile Steel with a high level of carbon.


In general, mild steel has a lower hardness than high tensile steel. In general, high tensile steel has a greater hardness than mild steel.


Steel with a low tensile is more likely to rust quickly and easily than steel with a high tensile. Steel with a high tensile is less likely to rust.

Corrosion Resistance:

Compared to high tensile steel, mild steel is more corrosion resistant than high tensile steel. But in comparison to mild steel, high tensile steel is less corrosion resistant than mild steel.


Mild steel is used in the form of rolled sections, reinforcing bars, roof coverings and sheet piles etc. High Tensile Steel is used for Pre tensioning or Post tensioning of prestressed concrete construction various kind of lifting, hoisting and pulling hydropower stations, atomic reactors and nuclear power stations.

With its unique properties, mild steel can be used to make steel frame buildings, machinery parts, cookware, pipes, fencing, and other structural components of construction projects. The high tensile strength of high strength steel allows it to be used for a wide variety of purposes, including reinforcement in automobiles, the manufacture of weapons, the aerospace industry, shipbuilding, etc.

In essence, carbon is an essential constituent of steel, giving it strength and hardness. As the percentage of carbon increases, ductility, malleability, and toughness are reduced in proportion. It is very clear from the article that Mild Steel is made from low carbon steel while High Tensile Steel is made from high carbon steel. There are many differences between Mild Steel and High Tensile Steel based on their composition, properties, and applications. The use of mild steel is preferred when a low budget and strength are required, whereas the use of high tensile steel is widely used when prestressed concrete structures such as bridges and large span structures are required.
