Description
25mm Diameter Black Mild Steel Round Bar - S275JR Grade
The 25mm diameter black mild steel round bar in S275JR grade is a highly durable and versatile material, ideal for a wide range of industrial and construction applications. Known for its excellent weldability, machinability, and formability, this round bar is a popular choice for projects requiring both strength and flexibility.
Material and Properties
The round bar is made from S275JR grade mild steel, a structural steel commonly used in construction and engineering. This grade is known for its combination of strength and toughness, making it ideal for fabricating load-bearing components. The S275JR steel grade provides excellent mechanical properties, ensuring that it can handle both static and dynamic loads, making it a robust choice for construction projects.
Formability and Weldability
This 25mm black mild steel round bar offers excellent formability, allowing it to be bent, shaped, or rolled to meet specific project requirements. Its ductile nature ensures that it can be manipulated into various shapes without cracking or losing its structural integrity. The bar’s exceptional weldability means that it can be easily joined with other steel components, making it ideal for use in fabrication and assembly work. The resulting welds are strong and reliable, perfect for projects that demand robust connections.
Machinability
With excellent machinability, the S275JR mild steel round bar is easy to machine and shape using a variety of cutting and drilling tools. Whether you’re working on precision engineering components or large-scale industrial parts, this steel bar can be machined to tight tolerances and precise dimensions. Its smooth surface and high machinability make it a favourite for engineers and manufacturers requiring high-quality steel for machining operations.
Corrosion Resistance and Finish
Like most mild steels, the S275JR grade round bar has poor corrosion resistance, which means it may require surface treatments or coatings for protection in harsh or outdoor environments. The bar comes with a mill finish, offering a raw, industrial appearance. While the mill finish is ideal for general use, protective coatings such as paint, galvanizing, or powder coating may be needed to prevent rust and corrosion in moisture-prone environments.
Applications
This 25mm diameter black mild steel round bar is widely used in construction, engineering, and fabrication. Its versatility and strength make it suitable for structural applications such as beams, columns, and supports. Additionally, it is used in the manufacture of components for heavy machinery, frameworks, and industrial equipment. With its excellent weldability and formability, it is ideal for both custom fabrication and standard industrial use.
