Introduction to Mild Steel
What is Mild Steel?
Mild steel, also known as low carbon steel, is one of the most commonly used types of steel. It contains a small percentage of carbon (typically 0.05-0.25%) which makes it more malleable and less brittle compared to higher carbon steels. This steel variety is known for its versatility, affordability, and ease of fabrication.

Properties of Mild Steel
Mild Steel Properties
Mild steel boasts several properties that make it an ideal material for a wide range of applications. These properties include:
- Malleability: Due to its low carbon content, mild steel can be easily shaped and formed.
- Ductility: It can be drawn into wires without breaking.
- Weldability: Mild steel can be readily welded, which is a crucial feature for many construction and manufacturing processes.
- Magnetism: Mild steel is magnetic, making it useful in various electrical and industrial applications.
- Density of Mild Steel: The density of mild steel is approximately 7.85 g/cm³, which is typical for most steel types.
Mild Steel Yield Strength
The yield strength of mild steel varies depending on its composition and manufacturing process, but it typically ranges from 250 MPa to 370 MPa. This strength makes it suitable for structural applications where significant force is applied.
Mild Steel vs. Other Steels
Mild Steel vs. Stainless Steel
When comparing mild steel to stainless steel, several differences arise:
- Composition: Stainless steel contains chromium, which gives it corrosion resistance, while mild steel does not.
- Strength: Stainless steel generally has a higher tensile strength than mild steel.
- Corrosion Resistance: Stainless steel is more resistant to rust and corrosion compared to mild steel.
- Cost: Mild steel is usually less expensive than stainless steel, making it more economical for large-scale projects.
Carbon Steel vs. Mild Steel
Carbon steel encompasses a wider range of steel types that contain varying amounts of carbon. Mild steel is a subset of carbon steel:
- Carbon Content: Mild steel has a lower carbon content (0.05-0.25%) compared to medium (0.30-0.60%) and high carbon steels (0.60-1.0%).
- Brittleness: Higher carbon content steels are harder and more brittle, while mild steel remains ductile and malleable.
Applications of Mild Steel
Mild Steel Tubing
Mild steel tubing is extensively used in various industries due to its strength and formability. It is commonly found in:
- Construction: For structural supports, scaffolding, and frameworks.
- Automotive: In exhaust systems, chassis, and other components.
- Manufacturing: For making machinery, equipment, and furniture.
Mild Steel Angle
Mild steel angle, also known as angle iron, is a structural steel shape with an L-cross section. It is used in:
- Construction: For framing, supports, and brackets.
- Engineering: In various mechanical applications due to its strength and versatility.
Welding Mild Steel
Can You Weld Stainless to Mild Steel?
Yes, it is possible to weld stainless steel to mild steel. However, this process requires special techniques and considerations to ensure a strong and durable bond.
Welding Stainless to Mild Steel
Welding stainless steel to mild steel involves several steps:
- Preparation: Clean both metals thoroughly to remove any contaminants.
- Choice of Filler Metal: Use a compatible filler metal, such as austenitic stainless steel filler, to bridge the differences in composition.
- Welding Method: TIG (Tungsten Inert Gas) welding is preferred for its precision and control over the heat input.
TIG Welding Mild Steel
TIG welding, or Gas Tungsten Arc Welding (GTAW), is a welding method that uses a tungsten electrode to produce the weld. It is particularly effective for welding mild steel due to its:
- Precision: Allows for fine control of the welding process.
- Quality: Produces high-quality, clean welds with minimal spatter.
