Steel vs Mild Steel: Difference and Comparison

Steel and mild steel can be confused with one another. Both metals are used for various purposes, largely for construction.

Key Takeaways

  1. Steel exhibits higher tensile strength than mild steel, making it suitable for heavy-duty applications and construction projects.
  2. Mild steel contains lower carbon content (up to 0.25%) than steel (0.25% to 2.14%), resulting in increased malleability and ease of welding.
  3. Steel offers better resistance to corrosion than mild steel, which requires protective coatings or treatments to prevent rust.

Steel vs Mild Steel

The difference between steel and mild steel is that steel is harder than mild steel as it has a higher carbon content. Even though mild steel is comprised of carbon as well, it comprises a variety of mixtures of alloys that steel doesn’t. This mixture of metals is made to have very specific characteristics.

Steel vs Mild Steel

Steel is a hard metal known for its strength and rigidness. It has a high carbon content which makes it brittle and durable. By virtue of this, steel is used to make various tools and cutting instruments.

Mild steel is a sub-variety of steel alloy. Carbon is one of its major components. Other elements may even include non-metals. Due to this, mild steel is not as brittle, strong and durable as steel.

What is Steel?

Steel is an alloy that is formed from iron. It is used for manufacturing tools for construction. It has a very high carbon content, making it strong, durable, hard and less malleable.

One of the most widely used types of steel is alloy steel. Such a property makes it perfect for being used to build automobiles such as cars, trains, buses, and even aircraft parts.

When iron is in its pure form, it is not very hard. Therefore, it is not very manageable to use as a construction material. This pure form of metal is made into steel alloy by adding carbon to it.

The history of steel can be tracked down to when three French scientists distinguished and identified the nature of the metal. Steel was officially defined in 1786, however, it was not until the 19th century that production started on a larger scale.


What is Mild Steel?

Mild steel is a type of steel that is made up of the element ‘carbon’. However, this element is present in very small quantities. Moreover, there are a lot of other metals and non-metals that are used to make mild steel.

Since the carbon content of this alloy is very low, it is very malleable. This makes it easy to use for building pipes, hinges, nuts, screws and bolts.

Mild steel also contains low amounts of chromium, molybdenum and other alloying elements. Since the carbon content is low, the metal is malleable, ductile, easy for machines and affordable as compared to others.

A common method to produce mild steel is from iron and coal. First, these elements are extracted from the ground and then melted together.
