3/8" (9.5mm) Diameter Mild Steel Round Bar - Bright Finish Strong Durable Precision-Cut Metal Rod for Fabrication Engineering, and DIY Projects - Linear Metre

3/8" (9.5mm) Diameter Mild Steel Round Bar - EN3B Grade

The 3/8" (9.5mm) diameter mild steel round bar is a highly versatile and popular material in the world of fabrication and engineering. Its combination of durability, ease of use, and cost-effectiveness makes it an excellent choice for both professional engineers and DIY enthusiasts alike.

Material and Composition

This round bar is made from mild steel, specifically EN3B grade, which is renowned for its excellent formability and machinability. EN3B is a low-carbon steel with a well-balanced blend of properties, ensuring that the material is not only easy to work with but also delivers strength where required.

Formability and Machinability

Mild steel in this form has good formability, allowing it to be easily bent or shaped without the risk of cracking or breaking. This makes it ideal for projects that require custom shaping or intricate designs. Additionally, its excellent machinability means it can be cut, drilled, or threaded with minimal effort, making it a go-to material for projects that need precision and adaptability.

Weldability

Another major advantage of the 3/8" mild steel round bar is its excellent weldability. Whether using MIG, TIG, or arc welding, this steel readily fuses without issues, offering clean, strong welds. This makes it particularly useful in structural applications where reliability is paramount.

Strength and Durability

Although mild steel does not have the high tensile strength of alloyed steels, it is still remarkably strong for most general-purpose applications. It holds up well under stress, which is why it's commonly used in construction, manufacturing, and automotive repairs. With a weight of 0.558kg per metre, the 9.5mm diameter round bar provides an ideal balance of strength and weight for a wide range of tasks.

Finish and Corrosion Resistance

The round bar comes with a mill finish, giving it a clean, smooth appearance. However, it is important to note that mild steel has poor corrosion resistance. When exposed to moisture or harsh environments, it will begin to rust unless treated with a protective coating. For outdoor use or in environments prone to corrosion, applying paint, oil, or galvanising the steel is highly recommended to extend its lifespan.

Applications

This steel round bar can be used in various applications, including:

• Fabrication projects: Ideal for creating frameworks, brackets, or supports.
• Engineering: Frequently used in automotive, machinery, and industrial components.
• DIY projects: Perfect for home improvement tasks, such as building furniture, shelving, or garden structures.

In summary, the 3/8" (9.5mm) mild steel round bar is an excellent choice for projects that require strength, precision, and adaptability. With its good formability, excellent weldability, and wide range of applications, it's a cost-effective and reliable material for professionals and hobbyists alike. Just remember, due to its poor corrosion resistance, a protective finish is essential for ensuring long-term durability in outdoor or moisture-prone environments.
