15mm Diameter Mild Steel Round Bar EN1A Grade, Mill Finish, 1.4kg/m, Excellent Machinability, Poor Weldability & Corrosion Resistance, UK Stock - Linear Metre

The 15mm Diameter Mild Steel Round EN1A is an excellent option for applications requiring precision machining. This steel round bar is made from EN1A grade mild steel, a free-cutting steel known for its high machinability. It has been specifically engineered to offer outstanding performance in automated machining operations, making it a preferred material for high-speed production.

Key Features and Benefits:

1. Exceptional Machinability
One of the standout qualities of EN1A mild steel is its exceptional machinability. This grade of steel is designed to be easily cut and shaped without excessive wear on tools, making it ideal for complex turning, drilling, and milling operations. Its superior machinability significantly reduces machining time, leading to increased productivity in manufacturing processes.

2. 15mm Diameter and Mill Finish
With a diameter of 15mm, this round bar is versatile for a wide range of applications. Its mill finish provides a clean, industrial appearance, perfect for machining applications where aesthetics are not the primary concern. The mill finish is also an economical choice, as it requires no additional surface treatment for machining tasks.

3. Poor Formability and Weldability
While EN1A steel offers excellent machinability, it has poor formability and weldability. This makes it less suitable for projects requiring significant bending or welding. It’s best used in environments where precise cutting, shaping, and drilling are essential. The alloy's composition, with added sulphur, enhances its machinability but reduces its suitability for forming and welding.

4. Corrosion Resistance
The 15mm Diameter Mild Steel Round EN1A offers poor corrosion resistance, which means it should not be used in environments where it will be exposed to moisture or harsh chemicals without appropriate surface protection. It is often treated with coatings or other protective measures if corrosion is a concern.

5. Weight and Strength
Weighing 1.4 kg per metre, this mild steel round bar offers a balance of strength and weight. It is strong enough for mechanical applications, especially in producing precision components such as gears, shafts, and fasteners. However, its poor corrosion resistance makes it more suited for indoor applications or components that won't be exposed to harsh weather conditions.
