15mm Diameter EN8 Mild Steel Round Bar High Strength Engineering Rod Precision Machining, Welding & Construction Material - Linear Metre

15mm Diameter Mild Steel Round Bar – EN8 Grade

The 15mm diameter EN8 mild steel round bar is a versatile and reliable material widely used in engineering, construction, and general fabrication. Known for its medium carbon content and superior mechanical properties, EN8 steel offers high strength and hardness, making it an ideal choice for applications requiring both durability and performance.

Material and Composition

This round bar is manufactured from EN8 mild steel, a popular medium carbon steel known for its balance of toughness and machinability. With a carbon content that gives it greater tensile strength compared to lower carbon grades, EN8 is ideal for parts subjected to stress and impact.

Formability and Weldability

Despite its increased strength, EN8 mild steel retains good formability, allowing it to be easily bent, shaped, and worked with in various processes. Whether you're cutting or forming the material, the 15mm round bar handles these tasks effectively. Additionally, it boasts excellent weldability, allowing strong joints without compromising the integrity of the material, making it perfect for welding operations in industrial applications.

Machinability and Performance

One of the key benefits of EN8 steel is its excellent machinability. The 15mm diameter round bar is suitable for turning, milling, drilling, and other precision engineering processes. Its ability to withstand heavy-duty machining makes it a preferred choice for components such as axles, shafts, and gears, where precision and strength are paramount.

Corrosion Resistance

While this round bar excels in terms of strength and machinability, it is important to note that EN8 mild steel has poor corrosion resistance. It is not suitable for environments with high moisture or exposure to the elements unless treated with protective coatings or used in combination with corrosion-resistant materials. For indoor applications, it performs exceptionally well.

Finish and Appearance

The mill finish provides the round bar with a standard, clean appearance straight from the rolling mill. This smooth surface makes it suitable for projects where aesthetics are important, though additional polishing or surface treatments can be applied to enhance the finish depending on the requirements of your project.

Applications

Thanks to its combination of strength, machinability, and formability, the 15mm diameter EN8 round bar is commonly used in a range of industries. It is perfect for manufacturing heavy-duty components such as axles, shafts, studs, gears, and other mechanical parts. It is also popular in automotive, construction, and precision engineering sectors where high strength and reliability are essential.
