25mm Diameter EN1A Mild Steel Round Bar: A Versatile Solution for Precision Engineering
The 25mm diameter EN1A mild steel round bar is a popular choice for a wide range of industrial and engineering applications, offering an excellent balance of machinability and versatility. Known for its outstanding machining properties, this steel round bar is designed to meet the demands of projects where precision and quality are essential.
Material and Grade
Made from EN1A grade mild steel, this round bar is specifically engineered to enhance machinability. EN1A is a free-cutting mild steel that contains sulphur, making it ideal for components requiring close tolerance, fine finishes, and high production rates in automated machining processes. Whether for turning, milling, or drilling, EN1A ensures an efficient and smooth operation, making it a preferred choice for complex, high-volume production tasks.
Excellent Machinability
One of the standout features of this 25mm mild steel round bar is its excellent machinability. EN1A grade mild steel is often used in applications that require intricate machining due to its free-cutting characteristics. This property significantly reduces tool wear and enhances productivity, making it an ideal material for CNC machining and other precision engineering operations.
Weldability and Formability
Though EN1A excels in machinability, its weldability and formability are considered poor. Due to the sulphur content, the welding of EN1A is not recommended for structural purposes without special precautions, such as using filler materials or post-welding heat treatments. If welding is required for your project, alternative steel grades might be more suitable.
Similarly, the formability of EN1A is limited, making it less ideal for applications where bending, shaping, or forming is needed. This round bar is best suited for applications where machining is the primary focus.
Corrosion Resistance and Finish
The corrosion resistance of this EN1A round bar is poor, so it's generally not recommended for outdoor or marine environments without additional protective coatings, such as galvanizing or painting. The bar comes with a mill finish, which is a standard, unpolished finish commonly found on steel products. This surface may require further treatment depending on the aesthetic or functional requirements of the project.
Applications
The 25mm EN1A mild steel round bar is widely used in the production of precision components such as nuts, bolts, hydraulic fittings, couplings, and shafts. It is particularly well-suited for high-speed turning and other machining processes where a high-quality surface finish and tight tolerances are required. This round bar is also a great material for making parts in the automotive, industrial machinery, and mechanical engineering sectors.
Weight and Dimensions
With a diameter of 25mm and a weight of 3.89 kg per metre, this round bar offers the strength and stability needed for many engineering tasks. The consistent diameter and uniform shape ensure that it performs reliably in automated and manual machining setups.
Conclusion
In summary, the 25mm diameter EN1A mild steel round bar is an excellent material for precision machining, offering superior workability in manufacturing processes. While it may not excel in weldability or corrosion resistance, its key strengths lie in its machinability and suitability for mass production of components with fine tolerances. For industries focused on high-quality machining, this steel round bar is a dependable and efficient choice.
